XP : TortoiseSVN and Explorer

We've moved from VSS to Subversion and I downloaded TortoiseSVN as my Windows client.
Every time I right-clicked on a folder, I get"

"Windows Explorer has encountered a problem and has to close"

Mr. Google to the rescue - took me a while - but eventually I discovered that the problem was with PowerDesk which I rarely use anymore.

So I uninstalled it and now all is well!

Enjoy!
