Can't drag and drop?

This is the second time this has happened. I can't drag anything anywhere. Not on the desktop, not in finder, nothing. Any ideas?

 

This just happened last night and I rebooted last night and it fixed it...but come on, I have to reboot daily? I'm sorry, I think I got a Mac built on Super Bowl Monday (jk, I know they don't have that in China)...

I am having another issue with a site I just built. I have bridged a gallery and a forum and with all three browsers, the bridge doesn't work for me. But, with my PC and the PC of the client I built it for and the people at the support forum for the gallery who provide the bridge, it works fine.

It just seems to be one thing and then another with this machine that I thought would make my life better.

*okay, vent over *

Rebooting now...
