The On_Update_UI event is normally used to disable macros (they are always enabled unless disabled) using the DisableMacro API. I think you should look at the logic you have in place inside this event to see if it is incorrectly disabling a macro associated with a toolbar button. For a detailed description of how it works with toolbars see the XMetaL Developer Programmer's Guide topic called “When the context changes”.
There are no other useful events or APIs that I can think of that you would be using. But if you need further assistance I think it would be best for you to send your customization to XMetaL Support to have them look at it. Without knowing what you are doing I don't think anyone would really be able to guess what's causing your issue.
