Hi

Based on my test, I can not reproduce the problem.
To isolate the poblem, I think you may try to show a msgbox in the ShowForm
Button or even just debug.print "test" to see if the problem persists.
Also I think you may try to create a new workbook on another machine to see
if the problem persists. This will help us to know if the problem is
workbook specific or machine specific.

If you still have any concern please feel free to post here.

Best regards,
