Hi,
Perhaps that is the way Excel 2010 does things, and perhaps the macro project is protected from viewing by the user. If the latter is the case, remove the protection and try again. In the former case post the code that causes the problem. It is one of the objects in the code that XL10 handles differently from XL07. People familiar with both may be able to tell from their experience. I won't, because I don't have such problems.
In fact, if you can identify the object (with the help of the Debug key) you may be able to google for a cure because such changes are usually well publicized both, by MS and other users facing the same dilemma as you do.
Post something that the experts can get their teeth into, and I'll wish you the best of luck.
Have a great day!

I do this for "honour and country" - much less of the latter, actually.
If I helped you, award points, plenty of them.
If I bored you, deduct points for being too long-winded. (I know, :lol)
