Mac OS X Leopard FIX: can't click on icons on desktop

Ok.  This is really strange.  

I was fiddling around with gsync and its settings.  (btw, check out this amazing tool to synchronize your Google calendars with iCal.  It's great!)

I don't know if what I was doing with iSync and gsync had anything to do with the problem that suddenly came up, but here is what happened:  all of a sudden I could not interact with my Leopard desktop anymore.  I would click on icons, and nothing would happen.  I couldn't even double-click on my HD icon to open it.

I googled away but couldn't find any answers.  Finally, I decided to download TinkerTool, which allows you to set hidden system preferences.  Now here is the funny thing:  I downloaded TinkerTool, I double-clicked on the icon to run it, and suddenly my Leopard desktop was working fine again!  I didn't even have to fiddle with any hidden preferences.

Is that weird or what?

Summary of fix:  If you can't click on the icons on your Mac OS X Leopard desktop, try downloading and running TinkerTool.
