I am using the "Application.ontimer" member of the excel library  to call a Public Sub GetTime()

I am getting the error "Cannot run the Macro "GetTime" May not be available in this  workbook or all...."

I've changed my security setting to "none" in Microstation XM, is there a place where I should look to see if macros are disabled?  I am running other vba, with no problem.

Thanks in advance.
