Windows Explorer has stopped working?

I have OS Windows 7 RTM. Sometimes when I click on some folders or some of partitions there's an error "Windows explorer has stopped working". Can I fix this? Does the same mistake exist on the Windows 7 full version? Thanks

Are your partitions corrupt? Do you have any shell extensions that haven't been tested with Windows 7 installed?

RTM is the final version, and it's highly unlikely they'd ship with such a bug, so it must be a problem with your setup.

Are you running Firefox in private browsing mode on Windows 7 x64 by any chance? There's a known bug in the Windows clipboard API when switching from a 32-bit application(for example, Firefox) to a 64-bit one, and it tends to cause explorer.exe to crash.

See the following bug report on FF's bugzilla

Anyhow, it should be fixed in a future release (If you're really anxious, Firefox 3.6 beta 5 already includes the fix but being a beta release it may have other stability issues)
