Hi Nigel,
There's some behaviour of TRulerbox that's causing me problems:
I have a ruler box with 2 grips and triangles for grips.
When I try to move a grip to the far end of the ruler and the mouse accidentally moves a little further outside the ruler (keeping the left mouse button down) everything (a lot anyway) in my program stops.
I removed the rulerbox change event to make sure nothing in there caused the problem. No effect.
The problem for me is that an event from a background process is not responded to any longer.
Just to check I also have a timer running in the background which a few times per second updates a label on the form. Updating goes on happily as long as I don't try to drag the grip across the left or right border. Then the timer halts until I release the mouse button or move the mouse inside the borders again.
Trying to force the grips positions in the change event to stay within the borders (adding/subtracting 1 position unit from the left and right limits, which are 0 and 255, did not help.
Neither did an attempt to set the focus somewhere else.
Do you have a suggestion? The problem is not just cosmetic.
Regards,
Jan Steevens
