MS Toolbar control freezes

[theintrepidfox]

Dear Group

When I call the code below within the click event of a MS Toolbar
control, the code is executed and works fine but the Toolbar freezes.
When calling the same code from a webform button, everything works
fine. Is there any explanation for this behaviour?

Thanks very much for your help & efforts!

Martin
