not possible to do a true drag vs click
I did not tell that. I do not know your application.
Mine is Picture Puzzle where I use 'drag control' to swap picture tiles.
Try the following:
That did the trick quite nicely, thanks!
Honestly, I am pleased when somebody finds 'help' in my post. Most of my replies in Ask-for-help do not attract a reply from the original poster.
Well, you won't get that kind of ingratitude from me.
Incidentally, I'm still encountering visual glitches, even with the additional Redraw.
I'm using PNG's with transparency, and if I stack several of them with partial overlaps (like the way you'd fan a hand of cards), then grab another one and pass it over the whole stack left or right - after a few passes, there start to be problems.
Sometimes it's that the second image from the top all of a sudden becomes the top image. Or we can get all kinds of visual "jump through".
I tried "dllCall("UpdateWindow", UInt, sHwnd1)", as TLM suggested, but it didn't seem to make a difference.
