Hi all,

I am facing one weired problem. I am adding one menu item to the right
click context menu for my add-in. I pasted my function below.
This function is working fine with Outlook 2002 and Outlook 2003. But
it is crashing on Outlook 2000 for one specific scenario.
After initializing Outlook if I right click on normal mail item and
then if I right click on meeting item Outlook just crashes with the
Access violation error.
Only difference between these two menus are for meeting item there are
more no of options in the context menu.
If user does it vice versa then it works fine. ( first right click on
meeting item and then mail item.)
I am not able to understand this behaviour of Outlook 2000. If anyone
knows about this issue, please let me know about the same.

I have noted down the crash line as "*******Crash occurring here.
*******" in the code.
