I'm working on a form which has a command button to clear the fields and reset the form. It usually works fine, but sometimes it stops responding to the mouse at all. It doesn't even appear to depress. Unprotecting the document, enabling Design mode, then disabling Design mode and re-protecting the form will get it working again. At least for a while.

I've seen some references to command buttons not working on protected forms, but it does work most of the time, so that's obviously not the case. Can anyone suggest what the issue might be and how I might work around it to ensure the button works every time for the users of the form?

Thanks
