David,
It's odd alright. I looked inside the .scx and saw that the name property was set to "frmMonDisp", even though last time it was displayed in the form designer it was "FRMMONDISP". Closed the .scx; opened the project, opened the form and the property box showed "frmMonDisp" - and always shows it that way again. ????!!!
Oh well...

You close the form (.scx) and the case changes to UPPER for no discernable reason when it's next opened (even immediately). The form in question is a great grandchild of the base class. I had made no significant changes to the form and the form works just fine in all other respects.
