Evaluation Example Dock Widgets Hangs Windows

[inflector]

Funny, I just read your reply to another question and noted the reference to the but database entry there. Thinking that it was likely to be a reported bug if anyone saw this before I searched for dock and mouse and found the following:

This appears to describe a cause which would give the symptoms I am seeing based on my previous experience having screwed this up myself before (repeat after me "I hate Windows"). It also seems to be a problem introduced in 4.2 which fits my experience.

Unfortunately, I can't evaluate 4.3.

Oh, one more possibliity.

It may be that this problem does not show up unless you are running a dual processor machine just based on the way threading works on single versus dual processor machines. This would explain why something so obvious as dragging a dockable window in the dockable window application wasn't picked up by QA.

This is something fairly new in the Core Duo laptops like the T60p.

It is possible that on a single processor machine there not enough processing for background applications for them to get to this state.

I had the exact same problem.
I've got a Thinkpad R50p (single core pentium mobile 1.6GHz) with a custom Dutch Windows XP installation.

I fixed it by reinstalling QT and rebooting after it, I don't know why it worked but it worked.
