The following code shows a bug in _GUICtrlTreeView_GetNext.

The bug also affects _GUICtrlTreeView_FindItem; this routine will enter a infinite loop when the searched text is not found in the tree-view, because it relies on _GUICtrlTreeView_GetNext to return zero when called for the last item. (Thus prio Major)

Hello,

I developed an application with visual c# under windows xp. This program uses autoitx3.dll. Everything worked fine until I upgraded the system. With the new cpu (64 bit) - still under xp - the pixelchecksum function (aprox. in the half of the cases) returns wrong values (-2147483648).

After this, I tried the program on two more machines with Intel P4 cpu, and the results was the same.

I tested the checksum at these machines with autoit main too, and that worked perfectly. So I think the problem is in autoitx.
