I've made some workbook-specific addins. I distribute them to other users
besides myself.

I'd like to change the extensions on these addins from "xla" to another
three-letter extension. I'd like to know if this will cause any problems in
Windows or Excel. I'm not talking about coding issues, but just wondering
if changing the extensions could cause the addins not to work as well as if
I kept the default extension.

These addins are running on XL 2000 on up.

Thanks,

Doug
