I'm building an application in Excel 2007. The first worksheet is a menu sheet with 2 x labels, 2 x text boxes and 1 x command button. On other sheets there are command buttons which run macros to perform various functions. Once I take the workbook out of developer mode, each time someone clicks a button or clicks into a textbox, the text shrinks and after several uses disappears. It also occurs on labels (I found this out when I accidentally clicked one). The labels I can protect but how do I stop this happening on command buttons and text boxes.

Thanks for your help
