Visio Toolbars Disappear!

Hi,
When I create a custom toolbar in Visio 2000, then close and reopen Visio, my toolbars have reverted back to just the standard toolbars. I have to go and recreate the custom toolbar each time.

Any ideas??

Ideally I'd like something likethe Normal.dot for Word, but can't find Visio's equivalent. What I eventually want to do is to have all users using the same custom toolbars and settings.

Any help appreciated!
Gary
