Yes, I know what you were referring to

Nothing personal Tushar, but I wasn't replying to you. It was a follow
up to the OP based on her comments above, subsequent to my first post.
The use of "Application" was just for the sample code - having a local
variable referencing the Application is fundamental with COM Add-ins so
I didn't think it was worth mentioning.

I haven't tried it, but through Interop the modality of the
Application.InputBox should be the same (i.e., non-modal).
