Render Freeze - Please Help

[mancunian]

But there must be a way to avoid this, because there are applications which do not stop working when being dragged.

Can you name any Microsoft applications that do this?

Yes as i said earlier Windows Media Player continues to play video while being dragged as do most other non-Microsoft players. Don't know how they manage it

Don’t have the time to test it right now, but I think that it will stop the primary/gui thread. So maybe if you’ll run a second thread that will do the actual processing and drawing it will still work.

If non of you will I can try and test it tomorrow.

Thanks. I'm not familiar with threaded apps, so if you do get it to work could you please post the code for the setup/render loop
