I added several ActiveX control buttons to my excel xlsm file, each running different codes. Text on the button gets smaller after each click finally becomes unreadable after four or five clicks. and sometimes button sizes would also change randomly. (auto-size is set to false) I would have to open the developer mode and select the button, resize it and close it to set the text size back to what is listed in properties. BTW properties settings: caption text size never changes as text gets smaller.

Any ideas?
