Windows 7: Problem with Logitech Mouse in Windows 7 x64

I'm having a problem with my Logitech mouse in Windows 7 x64

1. When I try and highlight words to either copy or delete them, the words highlighted will either move to the front or will unhighlight when i let go of the mouse button.

2. When I right click in Windows 7 x64, Windows Explorer crashes.

Any ideas how to fix these annoyances?



PS I've reformated my PC countless times and these issues continue to come back but only in Windows 7 x64.

You need to reinstall the Logitech mouse driver in Vista compatability mode by right clicking on the file and choosing to install in Vista compatablity mode. I would uninstall the driver first and restart.

After you attempt this the first time there will be a long delay 10-15 seconds, at which point Windows will show you a prompt to reinstall using Windows compatablity mode, say yes to this prompt. After that Windows will reinstall those drivers correctly. Everything will work properly after you do that.

I'm using the same driver and that was the only way to make it work correctly. It should also fix your Explorer crashing problem. This procecure has already worked on a bunch of other machines running Windows 7.

Thanks for the help but I believe I found more of the problem than Logitech. Seems like Comodo Internet Security sees Windows Explorer as a threat in Windows 7 x64. If set in training mode CIS tends to automatically shut down explorer.exe. When in normal mode it continue flashing a red warning message.
