Coalesced updates and refresh rate

Hi,

I have a problem with the rate at which coalesced updates refresh the
window. We draw some animations outside the drawRect method, using
lockFocus/unlockFocus, but these drawing operations are only flushed about
ones a second. The do get flushed on mouse moves though. Is there anyway, I
can inform the window that graphics need to be flushed ?

I want to avoid calling CGContextFlush as that puts break on the refresh
fresh rate, if done wrong. CGContextSynchronize did not help.

Thanks
Wolfgang
