    Same bug here. You can open the Windows task manager and watch the GDI objects. If a Zoomer (and on my computer a Picker as well) is enabled you are able to create about 1000 GDI objects per second. After about 10'000 GDI objects Windows isn't happy anymore.

    (About 50% of the Qwt demos crash on my computer when I recompile everything with Qt 4.5.0 rc1 (when I move the cursor over a plot), but this is maybe my problem).
