Bad Vista!
Well, Vista does not support OpenGL in the way I've been using it to display the preview and the full-up screen saver. I don't think all hope is lost just yet, I just need to get my developent environment setup and working in Vista.
Wanna see a Vista error?

The good news is some of my older software (like this
mingolf game designed originally for Windows 98) is appearing to work without updates...
Vista support?
I plan on picking up a copy of Vista for my home computer next week, so I should be able to troubleshoot the issues Windows Vista users have been reporting.
Stay tuned.
