Region capture causes black screen

  Running HyperSnap 7.14.0.1.  When I do a Ctrl-Shift-R, to capture a region of the screen, the cross-hairs and guidelines appear, but the entire screen goes completely black.  Fortunately, the desktop reappears when I hit Esc.  Usual stuff - uninstall/reinstall, cold boot, etc.  but the problem persists.  I have dropped back to 7.13.0.5, and karma has been restored.
Environment:  Win 7 Pro, SP1. 
Help, please!
Thanx
