Hi, To (3): Error "0x00000005" is the famous "General protection error" i.e. your program changes memory that belongs to another application. This may be a simple usage of a nullptr, or the problem you already detected in (2).
You can create Release code with debug information and may get information where the problem comes from. If you try to find this error you will IMHO probably be better off if you debug with Visual Studio directly. To (1): To find leaks on WINDOWS you can use the free tool "Visual Leak Detector", though I am not sure whether the current version still works with VS 2010. - Michael. _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
