I use the latest level of Flash and have no problems. I use Chrome with the built in Flash disabled.

Have you tried clearing the browser Cache and the Flash Cache? The Flash cache is cleared at http://www.macromedia.com/support/do...manager07.html and then clicking on "Delete all sites". While you are there click on Global Storage Settings and move the slider to unlimited.

Shut down and restart the browser after doing that.

Also make sure that you have cleaned all temporary files and defragmented the hard drive. After defragmenting, reboot so the the Windows Paging file gets reallocated.
