I have some Excel files that include Macros written in VES. Recently,
I updated my Macintosh. I now use an Intel Core iMac, running OS X
10.4.7. I am using Excel for Mac Release 1. For some reason, some of
my files with macros will not work, or even open. When I try to open
them, I get a message that says "Error in loading DLL," then the file
closes.

These files work on every other machine I've tried, including my
trusty old G3 iBook and both of the PCs at work.

What's going on??
