>I have a button on a mmBusinessForm with the ToolTipText set. The tool tip works fine until I click on the button, then it will not appear again until I close and reopen the form. Is this the intended behavior? Have I hosed something up?

I just tried this on the MM .NET Windows Forms sample app, and the ToolTipText doesn't go away after clicking the button, so I'm not sure what's happening on your form...

Best Regards,
