Hi,
(magicdraw (MD) 17.0.1) Suggestion; nested drop-down and pop-up menu's should have some tolerance when navigating (with the mouse) to the next level. This is common feature for modern menu GUI's.
When navigating within nested menu's people tend to cut corners, with MD you need to precisely follow a menu selection area to get to the next level (if present), this can be relaxed a bit.
