Sticky Cascading Menus?

[Chris Quinn <cq htec demon co uk>]

Hello list,

I've just joined the list after having scoured the gtk header files, mail archives and faq for the answer to 
my seemingly trivial problem... so my apologies if I am insulting the collective intelligence of the list!

I was putting up with having to keep the left mouse button depressed while navigating a cascading menu, lest 
it should disappear 4-deep and force me to start again! I then noticed on another box using the framebuffer X 
server, that each menu only required a click to remain posted, and so I could navigate with a relaxed hand. 
Although this anomaly I am sure is not down to gtk, I am wondering if there is a way to ensure this behaviour 
through the gtk interface. After trawling the headers I am no closer to a solution.

Does anyone have the answer?

Thanks,
Chris Q.
