I have a userform that comes up when the workbook opens. I am randomly
getting an error box come up that says "Microsoft Userform" as the title of
the box and "Exception Occurred" as the error message. I click OK, and it
goes back to the userform, but when I click on anything else after that, I
keep getting the message popping back up and I can't do anything (even close
Excel down) without closing down by using the Task Manager. What is causing
this error and what can I do to fix it?
