explorer kind of freezes after resume from hibernation

It's been a week since I've notice that when I resume from hibernate, a
little problem starts happeing with Windows Explorer. The left panel in
windows explorer (the one that shows the folders) just stops working. When I
click on a folder it just don't open in the right panel. But when I click
direct on the exactly same folder at the right panel, it opens normaly.

I've been looking for an answer in this forum, but none of the hibertation
problems seems to be of this kind.

Thanks in advance for any help.
