AA_DisableWindowContextHelpButton not working?

[Megamouse]

Hi,

I recently changed my project from 5.8 to 5.10 and replaced all the flag settings for the ContextHelpButton with a QCoreApplication::setAttribute(AA_DisableWindowContextHelpButton);

But now every dialog shows the help button.
Any idea what could be wrong?

thx, megamouse

I'm updating to Qt 5.10.1 to see if anything changes
