[Ipe-discuss] Zooming and Qt 4.4

[Dmitriy Morozov]

Going through with the debugger, the freeze happens on the call to
QWidget::update() from IpeCanvas::Update(). So now I need to recompile
Qt 4.4 with debugging to see what's going on. Also I downgraded to Qt
4.3, and Ipe was back to working normally, so something strange
happens with my 4.4. My configuration is below

Best,
Dmitriy
