I don't think it would (it only stops the refreshes from being displayed), but you could save the forecolor settings, reset them to default and put them back when you're done.

>I don't like the idea of setting buffering to 1 and back to 5, it woyuld not work in our framework...

Why not, you set it and put it back within the same method - you're just making sure it's flushed to the disk. Maybe that part wouldn't be necessary at all.
