iroc9555,

Quite right there re COMODO CIS and XP. Over at the COMODO forums, I attempted to work out the issue in order to be able to provide a guide or path for others to try or follow in case they had the same sort of problem.

Turns out you have seen this before. I was unaware of this.

If one wishes to view or peruse the thread, go here: http://forums.comodo.com/defense-sandbox-help-cis/numerous-sandbox-defense-alerts-after-m-updates-for-8092011-t75270.0.html

In the end, I had to cut the chase short, as one setting change really compounded the problems I was having with the impact of CIS on the system. It finally got to be too much.

I suppose if this OS was, say, Windows 7, and this sort of problem occurred, this work might be more relevant, but still, strategies and techniques one learns along the way, can help others.

Interesting thing was, even the video driver was affected, as text on the screen would have minute dots within the letters themselves and not be as sharp as they are now after image restore.
