Videopad keeps Not Responding, Effects Screen Flashes

[tsr]

Hi. I've been using Videopad for a while, just posted a few days ago about an upload problem, now I've worked that out somewhat, but another huge problem popped up. I'm editing a video and anytime I try to do an "effect," the effects screen goes white, my mouse turns into an hour glass and the effects screen flashes- from white to flat out not existing, and eventually does nothing. Please, please help. Thank you.

To rule out CACHE corruption, open OPTIONS then click the DISK tab.  Click the "clear unused cache files" button.  Report back on whether that helped.
