1. Can you move this progress bar banner around?

   YES

2. Can you still use the main (VM Selector) window while this is
happening? E.g., open the File->Preferences dialog.

   YES

Anyway, please try to change the Qt theme (style) to see if that helps.

There is nothing in the drop down menus that will let
me change the Qt theme.
Why do you think the Qt theme has any impact
on the progress of the VM startup? If there
were a problem with the Qt libs, would not the
gui itself freeze or malfunction?

P.S. When posting the stack trace, it makes sense to do it for all
threads in all relevant processes. Yes, it's a bit of work, but VBox is
multi-threaded.


OK - I see what you meant. The stack trace of all threads
of the process VirtualBox is in the attached file.

Thanx to all who can get me past this hang.
