[Qt-interest] Stack overflow when using QAxWidget

[Gabi Julien]

Hi,

We have an application using Internet Explorer in an activeX. The Internet 
Explorer plugin is created and destroyed multiple times over a period of a 
few hours and then we get the stack attached to this email.  It's a stack 
overflow coming from QWidget. I should note that all windows should be native 
since the Qt::AA_NativeWindows was set at the application level.

Any help on this issue would be welcome.

We are using Qt 4.5.0 on windows XP sp3 and Vista sp1.

Regards
