Make both large and small custom icons the same

I just installed Acad 2010 LT on my boss's computer after much frustration with his custom toolbar buttons being clouds with ? marks I found that his small icons were the correct bmps and the large icons were not the right bmps I switched the display to show the small icons instead of the large ones and he is happy. I on the other hand dont like it. Is there a way short of going through every custom macro he has and copying the correct path from the small icon to the large icon box to change this? I know the above method works but that would be quiet time consuming. Any suggestions would be greatly appreciated.

Try this offer:

1- exit autocad, if it is running.

2- find acad.mnr in support folder.

3- erase it.

4- run autocad.

perhaps the problem will be solved!
