Every time I attempt to use my DV8P to run a presentation it develops new and ever-more-alarming quirks: The last time I used Miracast the DV8P disabled its wifi card. Today everything worked like a charm until I paired with a Bluetooth keyboard - and the Miracast connection broke and the Miracast device disappeared from the device list. Shutting down the keyboard caused the Miracast connection to come back to life - miraculously!

I've been using a Bluetooth "clicker" to run my presentations: Today the DV8P refused to recognize it. Then, after crashing the Miracast connection, it DID find and pair with the "clicker" - but then would not reconnect to Miracast. Finally, after fiddling around with it for an hour and rebooting the DV8P several time I managed to get it all working - for a little while: About fifteen minutes in, the DV8P would no longer accept commands from the "clicker" - not a problem, I could advance slides by tapping the touchscreen. 

...which worked for about five minutes until the touchscreen stopped recognizing my taps. Well, it would recognize the tap, but it didn't respond to it.

Has anyone else seen similar behavior?
