Hi,
There was a bug I reported a while ago that when starting to drag a control-bar, the control-bar lagged behind the cursor, when the process was having a moderate CPU consumption.
You fixed it so that the control-bar will ’jump’ to the cursor, and will not computer deltas.
This works, however, there is a notable time delay until the control-bar starts to move - and this gives a bad feeling. Please note that if the control-bar is focused, then the dragging begins with no delays, so there must be something you are doing in the focus changing.
You can reproduce it easily in the sample application we used to solve the bug.
Please note that just changing focus of the control-bars is lagged - put two control-bars one on top of the other, and make the one on bottom focused, it will take a notable time for it to become on top of the other control-bar.
Please look into it and fix it,
Thanks,
Ron.
