I see the same running your code under VFP7SP1 WIN2KSP2.

>I've currently written some code in a toolbar, that takes a little time to execute and does some manipulations regarding the graphical appearance of a control which is on the toolbar.

>During the processing I've done a THISFORM.LockScreen = .T. The longer the code took to run the more I noticed, that the toolbar's border went away during the lock. Below is some code, so anyone who wants can verify this behaviour.
