I have several users and myself as one. IE9 freezes up after a few minutes. Many times it will offer "Recover Webpage" at the bottom. Click on it and after a moment it will recover IE and repost the page. But after a few minutes it is frozen again. On my other users that have this issue, I uninstall IE9, back to 8. They never see the problem again. These are on mostly Windows 7 x64 PC's, some with factory Dell load, some with clean Windows installs. On my PC, going back to IE8 works fine, but this when it upgrades back to IE9, the problem is back. I decided to go ahead and upgrade to IE10 to see if that resolved it. Same issue. I have searched and searched and cannot find a resolution for it. Microsoft's trouble shooting tool says it cannot find any issue.
I have tried all the normal troubleshooting. Reset the browser, remove everything. Launch IE in safe mode not loading anything. The other day, I decided to try another user to determine profile issue. I logged on with a user that had never been on the PC and same issue. then I decided to try booting PC into Safemode with Networking and I could never reproduce the issue.
I certainly welcome ideas.
