????decreasing text??????
 

I have developed an excel spreadsheet containing several macros, combo
boxes and drop-down menus in Excel 97 (English version). I have two
problems.
1) Some users experience that the text in combo boxes and drop-down
menus are decreasing for every time you click them. What is wrong??
2) The spreadsheet does not work, struggles to calculate, get VBA
failure codes or does not even open for some users. Is there a problem
with later Excel version or Excel in other languages? Any
configurations that have to be done in VBA? What about add-ins? Any
suggestions?
