Re: wireless mouse causes some apps to blink? by peter

After some more experiments, I found a pattern:
Many apps (all??) that just gain focus would blink (noticeably repaints
itself) once within 1 to 4 seconds. Text based apps may not exhibits the
symtom, probably because text repaint is much faster. MS word initially
doesn't have this symtom, but after I draw some circles and rectangles in
the doc, then I can see the symtoms.
Here's one way that should show the symtom even on a fast computer. Run ms
publisher 2003, and insert a large photo (e.g. 10 megapixel). Then on top of
the photo, draw a filled circle. Lose the focus, and then refocus on
publisher again. You should be able to see the picture and the circle
repaint within 5 seconds. Sometimes they repaint themselves twice.
MS-publisher is chosen because it repaints photos slowly. If you have other
slow-repainting app, they would work too.
If I kill the ipoint.exe process, then the symtom disappear and the mouse
still works.
