I'm using Vegas 5.0. I had to reinstall Windows and all my apps recently (thank you MS!). After the reinstall, I notice in Vegas Media Pool window, my thumbnails constantly have to re-draw/reload when I open/scroll through the Media Pool. Not just the first time I open a project but anytime I scroll within. This never used to happen (several previous installs of Vegas 5). The redraws happen relatively quickly but it is still an annoyance/distraction. Any ideas?
