Alt key is sticky even though sticky keys is turned off

[Erik]

The Alt key is sticky even though sticky keys is turned off in kcontrol. 
This has annoyed me for many years so it is about time that I get it 
fixed. Whenever I accidentally touch the Alt key in any KDE program, the 
focus gets stuck in the menu bar. Also if I want to activate a menu and 
press Alt, but then change my mind and just release it before pressing 
any letter, the focus is stuck in the menubar. Other programs, like Dia, 
Thunderbird, Firefox, GNOME GhostView and XFig work just fine in this 
regard. Only the Qt programs have this undesired behaviour. How is 
sticky alt turned off?
