Hi guys,
I have a really annoying bug in my program that is hard to track down.
The situation is that when I repeatedly zoom in/out/in/out many times, at a certain point the program crashes. It looks like parts of the GUI are placed all over the desktop until after another couple of clicks windows reports an error and you have to end the program.
The point at where it crashes is unknown, but it does seem to crash quicker when a PC has less memory; i.e. the more memory, the longer it will take to crash. On a 512mB PC it takes about 20 zooms and on a 1G PC it must take around 80 or something (those are a complete guess though!).
I dont mean this in any disrespectful way because I think Qwt is excellent, and I use it all the time, but I've checked my program and I dont think that there is anywhere for my program to cause the crash, since all the data is passed to the plot via the setData function. So I can only assume that there is a pointer/allocation related bug somewhere in the QwtPlotZoomer code.

If you have any thoughts/questions I will be glad to help.
