This problem was fixed (at least as far as typing with your fingers)  on January 3rd.

You have to update the firmware for the touch screen.  Go to the Dell web site for the Drivers and Downloads for the Venue Pro Tablet (you can get there from My Dell on the Start Menu).  Look for the Firmware update marked Urgent - PanePanal Touch Firmware For Dell Venue 8  1/2/2014   Firmware_8T9WD_WN_1.0.4.2_A02.EXE   Vendor Version : 1.0.4.2   Dell Version : A02

Sadly, no, you aren't the only one having these touch related issues with the V8P. I'm on my 3rd device from Dell and I continue to have the same problems... single touch gets interpreted as multiple touches. I'm don't have the active stylus. Instead, I've had these problems when using my fingers as well as using a capacitive stylus.

There's a pretty lengthy thread covering this. You may want to check this out:  http://en.community.dell.com/support-forums/mobile-devices/f/4586/t/19533399.aspx

Unfortunately, after multiple replacements from Dell, I've given up on the V8P and will take my business elsewhere. There are other 8" Windows Tablets available (Acer, Lenovo, Toshiba), and the new Asus VivoTab Note 8 is expected to release in the coming months.

Good luck... I hope your experience turns out better than mine has.

I have had this firmware update installed since its release (I just confirmed it is installed).  The problem with multiple key taps remains.  I have noticed the following:

It is much much worse using a capacitive stylus than it is using a finger, but the problem remains when using a finger.

It is worse using the standard layout touch keyboard than it is using the default touch keyboard.

I have already installed that update. Unfortunately it didn't resolve the issue for me.

I really wish it was that easy. I've installed all updates, including the A02 touchpanel firmware. I've rebooted and confirmed that the firmware install was successful. The problem still exists.

I had only three days left on my return, so I took that option. I'm planning on waiting on the sidelines to see if this gets fixed.

I don't get it.  It worked for me.  Before the update, when I held a key down, it would repeat until I lifted my finger, since the update, holding a key down does not repeat.  I only get repeats if I get a little sloppy with my "touch", or if I use a (passive) stylus.

I didn't install all the updates.  I don't plan on going to China, so I didn't install the WAPI update.  The Delivery Application didn't look like something I needed, nor did the Dell Data Protection and System Management.  I Installed all the others, though I wondering if I needed TXEI driver.

I have a few theories as to why this is a bigger issue for some than for others...

1) Hardware\manufacturing inconsistencies - I've been through 3 of these tablets and have seen these inconsistencies, first hand. Just because each is labeled Dell Venue 8 Pro, doesn't make them the same... The first device was returned because it arrived to me with dead pixels. While I noticed that touch was a little flaky on this first device, it wasn't as bad as device #2 or 3. I also noticed a big difference in battery life across the 3 devices. My 2nd and 3rd device both have significantly more battery life than the original (~25%). While some of this may be attributable to updated firmware/bios and my charging habits, I did confirm that the battery in device #1 lost a lot more of it's design capacity than the battery in device #2 & 3. While I do believe there's a design flaw in the V8P's active digitizer, I also think that some of these devices are better than others. Unfortunately, I haven't been lucky enough to get one with touch response I would deem acceptable for my use.

2) Digitizer unable to tolerate "imperfect" skin - Due to some of my hobbies outside of work, my hands take a fair amount of abuse. As a result, my skin tends to be a bit dry and calloused. If I warm my hands up considerably and lube them up  with lotion, I've noticed a considerable improvement in the device's response to my fingertips. The reason I purchased this device was its mobility\portability. Unfortunately, when a tablet requires a bottle of hand lotion and an endless supply of screen wipes (to clean a greasy screen), I would no longer consider it highly portable. I have several other touch devices, including a Microsoft Surface and the Acer Iconia W3 (another 8" Win tablet), which have always tolerated my "imperfect" skin and provided close to flawless touch response. I've also tried more than one capacitive stylus and seen similar differences in how the V8P responds to touch. Therefore, I have to believe that the digitizer requires an unreasonable level of conductivity to achieve reliable touch response.

I noticed that the issue is more prevalent after I installed a screen protector. When I removed it the issues you mentioned generally go away.
