For anyone else following this, this turned out to be a conflict with the "WindowBlinds" software that sort of hooks into different programs and displays different graphical theme styles for desktop stuff and title bars, etc..

Something in WindowBlinds hooks into the save dialog that doesn't coexist properly with MoI. However, WindowBlinds can be disabled on a per-application basis and doing that solves this problem.

I'd consider this to be a bug in the WindowBlinds software, but I think I may be able to adjust a small thing in MoI for the next betea release so that this won't be an issue.
