Hi everyone. I seem to be having problems with my preview window. When I first start Sony Vegs, it seems to work fine. But after a bit of editing - and for no apparent reason - the preview window stops working (i.e., no video). The only way to recover is to save, reboot and reload the project. It keeps doing this and rebooting solves this issue but is time consuming.

Has anyone else experienced this problem, or know what may be causing this? I'm using Windows 2000, Windows Media Player version 9 and Sony Vegas version 5.0a. Any help would be gratefully appreciated.
