OK, I'm doing something stupid. User form has several elements including three text boxes. I paste data from Internet Explorer to the three boxes (Ctrl v). At some point, despite the original font size declaration at design time and again on text box change events, one of the text boxes (different boxes at different times) will shrink the font size to an unreadable level. I have to have done hundreds of userforms and never had this problem. The only thing unique is the VBA launch of Internet Explorer and the Ctrl v paste to the text boxes. I thought it might be an inadvertent keyboard short cut but I've tried real hard to keep my fat fingers away from the keyboard but to no avail. Win8, Excel 2013. What am I doing???
