ColorLine and 100% CPU usage

Hi

This may be related to the cursor tool problem.

When the ColorLine tool is dragged, CPU usage jumps to 100% and remains there until the mouse button is released, irrespective of whether the mouse is moved.

Interestingly, it happens only when DragRepaint == false. In this case, DoDragLine() is called repeatedly even when the mouse is stationary. If DragRepaint == true, it is only called when the mouse is actually moved.

I'm using the latest build (1.1.2259.29262), and the problem appears in earlier versions as well.

The issue for me is that I would prefer DragRepaint off, because I'm doing some extra stuff in a derived control, and would like to handle triggering repainting only when I need it.

Thanks

Hi Michael,

This bug is fixed in TeeChart for .NET v2. We will try to fix it in v1 as well and make another maintenance release including this fix.
