Works in Debug, Runtime Error in DLL

[Stephen Gailey]

Can anyone help? I have a major problem with a Com Addin I
have written for Excel.

The Application works fine if I run it from the VBA
environment in debug mode, but when I create the DLL and
use that I get the following Run Time Error:

Run time error
'-2147417846 (8001010a)':
Automation error
The message filter indicated that the application is busy.

The Addin has a number of menu options. Some of them
automate simply display dialogs at this time, and these
work fine. The more complex ones cause the error. These
ones include routines to create graphs and to automate MS
Project.

Any suggestions gratefully received.
