Hello everyone. It's been a while since I posted anything but has anyone here ever experienced a problem where the lower half of a display does not register mouse clicks? I have now noticed that my former ACD, a gateway 21". a BenQ 21" and a Samsung Syncmaster 2233BW all are "displaying" this same issue. It seems reasonable that it could be a bad GPU, but I wanted to get others' opinions before I tried to find a replacement for it. Now, when I am navigating either through a browser or even a stock OS X app, the lower portion of the display shows the cursor but most of it is not clickable. Only when I move the current active window or app higher up on the display will the items that were previously unclickable suddenly work. I initially thought that there were issues with the mice that I have (Razer Taipan, Apple wired mouse with trackball), but no matter the display that I choose or the port that I use on my stock GeForce 6600, this issue continues. The interesting thing is that the dock is not affected at all and works normally. If anyone has any ideas as to what I can do, please feel free to let me know.
