Error "it is illegal to call out when inside message filter"

[Roath Kanel]

hi, my friend have a problem as he told me below:

"I have been getting problems inside MS Outlook and cannot
figure out how to avoid it. Sometimes, as I am typing an e-
mail, I will use the Control Tab keys to switch from one
application or window to another.

Sometimes I get this message "it is illegal to call out
when inside message filter" and Outlook, combined with
Word, which I use as my editor, can get stuck/crashes."

does any one know how to solve this problem.

Alt Tab is the key to switch applications, not ctrl tab.
I do not know if this is causing the problem or not.
