WorkbookOpen event unpredictable
 

Have any of you come across a problem with Excel whereby if you have 2
different COM addins (VB6 code implementing the IDTExtensibility2
interface) that both subscribe to the WorkbookOpen event, then firing
the sink of this event is unpredictable.

e.g. 2 COM addins X & Y both subscribe to the WorkbookOpen event. A
Workbook referencing Addin X is opened, but does not have
its event trap for WorkbookOpen fired.

Any thoughts / work arounds ?
