Messenger plugin crashes explorer.exe in 64bit Windows 7

When the pc is brought out of sleep mode, explorer.exe imediately crashes.

I remove the Windows Messenger plugin everything is okay

This is a brand new PC/installation of Windows 7 64bit.

of course I have Messenger set to not automatically sign in when windows starts, either way.. same results
windows live messenger version is Build 14.0.8089.726
previouse Vista 32 bit OS this was not an issue

It's still doing it!

Explorer.exe crashing is clearly due to the messenger plugin. Anybody else experience this? I can't be the only one.
