Hi All, c1) clicking on the 3dboard doesn't always work, especially bad under vista with radeon mobility graphic cards, but I'm suffering from the same problem under Linux. The problem is that the pieces are redrawn to check if they have been clicked and that takes up to 1sec under windows vista with aforementioned cards. I'm not sure if it's needed to redraw the pieces, seems to work fine without.
The screen isn't redrawn, a simplified scene is rendered off screen to detect what was clicked. That being said it does use the same display list for the pieces, a slightly less accurate "piece" could be drawn which would be quicker, the reason I didn't bother is because this off screen "drawing" is very quick.
The fact it occasionally takes a long time to do this is likely a problem with the graphics driver, but maybe there is something that could be done in the code. It's difficult for me to try anything as I don't get the problem, maybe when I get a machine with Vista on it I might be able to reproduce it.
c2) the appearance settings crashes under Linux with 3d window managers. I have a work around for the problem, but I'm not even sure why it works. It's basically a gtkglext problem, but since that lib isn't actively maintained, we don't know when it will be fixed.
Seeing if replacing gtkglext with normal widgets is possible is next(ish) on my todo list...
