I am coding an Outlook addin using Visual Basic and CDO.  In my addin,
I have added several items to the "Tools" menu.  One of these menu
items starts a process that can take several minutes to complete.  A
second menu item becomes enabled only when this process is running, and
this second menu item is used to stop the process started by the first
menu item.

I am able to catch the menu button click event and start the process
with no proplems.  I have added a DoEvents call into the main loop of
my proccess to allow events to be handled while the process is still
running.  I am able to catch serveral types of events while the process
is running.  However, I cannot catch another menu button click event
while the process is still running, i.e. while the first menu button
click is still being handled.

Any ideas why i am unable to catch the second menu button click event?
An ideas how to fix/circumvent this issue?

Thanks!
