The fixes referred to by John Pollard do, indeed, work for many users including myself. Quicken contains some code that conflicts with other applications and Intuit hasn't fixed it and apparently has no intention of ever doing so.
What works for me:
- Not running Logitech Setpoint, that breaks Billminder and Logitech recognized the problem a couple of years back but seems unable to fix it. MSFT's Intellipoint works with a MSFT mouse and will work with a Logitech mouse only if it's plugged into the PS2 port, this has been verified on several different machines all running different flavors of Vista.
- Complete elimination of anything nVidia. I've personally had better results with ATI chipsets and video cards. The flickering problem is reduced or eliminated on those machines that have ATI chipsets and video.
The above may or may not work on all systems, it does work for me. I would think the information would be of interest to Intuit but they don't seem to be very interested?
