qPopupMenu behaviour

The behaviour of qPopupMenu has been bugging me for a while on KDE.
What i want to know is this behaviour just on my machine. Or is it a reported 
bug. When i have a large menu, the perfect example is the Bookmarks menu on 
konqueror, then it changes the menu behaviour. If i single click on any other 
menu, then the menu stays visible and moving the mouse highlights the menu 
items. But, if i have a menu that is taller than the screen, single-clicking 
does not work, the menu will disappear and a menu item will have been 
selected. In the case of konqueror, this is often "add new bookmark" dialog. 
To get the expected behaviour of the menu staying visible, i have to 
hold-down the mouse button. This is very inconsistent. It is already 
inconsistent in the way that the menu does not drop-down, but instead goes 
up, especially noticable if you have konquerors window half-way down the 
screen. This behaviour can also be reproduced with the desktop menu by 
creating loads of windows and using the window list menu.

Can i get some comments on this please?
