I think that this has been discussed before and the conclusion was that
it's related to the perpetual re-drawing of the copy progress dialog. 

Unfortunately, if you redraw it often enough, it slows things down, but
if you don't, then it's not interactive anymore...

I'm not sure whether there is a nice solution to this problem, other
than using background operations, when you know in advance that it will
take a lot of time.
