Behaviour when a new message is created from another program.

Hi,

When a new message is created from another program, I cannot use any other
Outlook windows.

For example, if I'm using Microsoft Word and use the "Send as attachment"
feature, or in Adobe Reader using the Email -- Send Copy feature, a new
message is created in Outlook with the document attached. While this new
message is open, I can't use any other Outlook windows. This behaviour
doesn't occur if I create a new message normally through Outlook.

I know this behaviour is probably designed, and not a bug, but why does this
happen and is there a way around it?

Thanks.
