Hi together,

I´m quite confused, what´s wrong in my programm. I installed qwt 6.0.1 on qt 4.7.2. Had some smaller problems on the creator plugin, but so long no problem, I fixed this issue.
Now I create a new dialog, with a QTabWidget item and placed a QwtPlot in it.
So far no problem. Because I like the whole thing, I introduced the lib in my project.
Compiled as debug, fixed missing headers and library references (Ok, it´s the debug build, no problem, checked this also for qwtd.lib and dll).
But when I close the dialog again my VS stops with a memory corruption from QwtScaleDiv.

I´m quite helpless, tried to strip the whole down, erased the tabwidget and so on, but have no idea, what´s wrong with the system. I have no drawing, or something else, only a nude widget.

Any help is appreciated,
kind regards,
Thomas
