Hey Michael, okay I just turned off my anti virus and the software went back to running smoothly.
I tried several different tests and they all had the same effect on sluggish redraw when antivirus on and fast smooth
redraw when anti virus is off.

I have updated the application and still no improvement.
I use zonelabs security suite. I wonder how to fix this?
any thoughts?
thanks
