Tab Focus : Controls outside of Form : resetting tab focus issue

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Click on a control not associated with a form
2. Click on a control associated with a form

What is the expected output?

The control with no form association should release it's tab focus as controls 
with form association do.

What do you see instead?

The control without form association maintains tab focus visual, thought the 
tab focus has moved to another control.
