Stuck on Right-Click in Parallels

[gauntrek]

Hi all,

I'm running parallels on the newest iMac and it's been working perfectly fine.
But now every time I click it only functions as a right-click, which makes using the virtual-machine really annoying. I've also been playing an MMO which was working fine but can't function much without the regular click function.

Another strange note:
When I hover my mouse over something in Parallels and then hit 'alt-tab' and scroll through the open applications and back to parallels, it automatically does a regular left-click.

I've tried resetting the computer, reopening parallels, changing mouses, resetting the wireless mouse, changing the mouse preferences...

Any ideas??

Thanks.
