Occassional screenshot failure

Every once in a while I will have this problem where I use the key-combo to select a region and don't get the crosshairs that I should get unless I click on the tray icon at which point the cross hairs show up but only appear when they're over the taskbar.  If I try that key combo again nothing happens and I can't select anything with my mouse until I take a screenshot of some part of the taskbar.  
I created a post about this problem a few months ago but I didn't have any way to demonstrate.  
Here's a screen capture of it happen:  http://dl.dropbox.com/u/1.7365/hypersnap_issue.wmv
When it starts I've already pressed my key combo for 'select region' and you can see the crosshairs don't appear until my mouse is over the taskbar.  I then have to take a shot of the taskbar, and then when I press the key combo again it actually works, but only because it doesn't happen if camstudio-recorder is running when I press the key-combo.
