My 6400 has a problem, last night I realised that Adobe Photoshop CS4 that I use needs Open GL to have all it's functions to work properly I Googled the ATI Mobility Radeon X1400 card and it says it has Open GL 2.0 which is what it needs but all I get when I open a picture in Photoshop is a black window and on searching it appears that it is an OpenGL problem?

So in my wisdom I went to the ATI site and upgraded to the newest firmware all went well but now when I start up Vista the screen stays bright for about the first couple of minutes during boot up but then suddenly dims to about half brightness, I realise that it's probably something that's loading in the startup thats causing this but does anyone know what this could be or how to find out?

The upgrade unfortunately didn't cure the black window problem I have in PSCS4!

Any help really appreciated...
