This forum is reserved for suggestions and complaints regarding the forums themselves...your question would be best asked in one of our technical support forums such as Computer Help. However, I will hit the key points on your issues.

* The resolution and color issue is likely caused by a display driver issue. The resolution would be to find out what graphics card you have, go to the manufacturer's website, and download the latest driver for your card. If you are unsure what graphics card you have you can use the free program Everest to find out.

* In regards to the uninstallation issue, make sure you exit the program first, delete any temp files, and try again. If you continue to have problems you can try removing it manually. That is, delete the program folder (in C:\Program Files) and then using the free program CCleaner to clean up the remains.

* Having files that cannot be defragged is normal since some are in use and protected. Unless there's an inordinately large number/volume then there's nothing to be worried about.

Hope this helps,
John
