Well for whatever reason, it works at 200 now. Both with the thumbnails stored in the database and not. However it doesn't work at 250 either way.

I see your point Sealed, if you set the thumbnails at 150, store them in the database and then up the size. Something could be going wrong there.

Andrei, does the database update the thumbnails when you change their size?

I also had the thought there might be a memory issue. Does the thumbnail view page have a memory limit?
