What can I say czar.. it works fine here, tested it several times until I gave up (300-600).

How many times did you try? You can always look at the code as its very straight forward.
I'm using XP Pro sp2, whats your spec?

It works fine for me. I have XP Pro sp2 as well. Well done tanffn

It's not a bad thing (may even be preferable to some). But it does add a professional touch to the app

Generally it works for me, but in your demo, the TImage freezes after several drags.... Then it doesn't render anymore, no matter if I drag or not.

Donno Huehnerschaender, maybe its something todo with TImage or TCavas and the fact that I didn't sync..
Anyway it was only to show the genral idea, I stated in the code its not the "proper way".
If many insist on working with Timage (which I doubt) I can debug the app.. :?

What's your computer spec? maybe its something to do with the CPU or its utilization(?)
I tested it on K7-1200, 1GB ram, with a crappy PCI video card. i'll try it at home as well.

I get the same effect but very infrequently. Sometimes the TImage disappears altogether, but the other form labels continue to update :?

The numbers in the timage stop updating after a short time. The image itself often dissapears. Numbers don't usually go higher than 10-15. I have run it about 6-8 times. Even recompiled it.

This is on windows xp sp2. 3 Ghz hyper threaded cpu, nividia 7800gs.

I go it to run up to 78 just before.

Tried it at home, XP3500-939pin (or something like that :roll: ) and I did encounter this problem as well..
The Image will disappear when you hide the window (move something over it) / background redraw as it is draws to the canvas.

NO idea way, first time I‚Äôve seen it this kind of problem.. I wander where does the Image go.. :eh:

This might have been said, and I might be behind. The rendering stops if form is set to Drag mode. Set the main form to dock.

In dock mode, clicking the main bar will not stop the timers or anything else. I had this very same problem with my project, it seems threaddedtimer carries on, dxtimer and other processes completely stop.

Use:

Object insprector Dragkind>>DKdock
