toolstripmenuitem

I have encountered strange problem with a three-level context menu. In some situation the sub menu does not show automatically. I have following structure of the menu:

* AAA - level 1
* BBB - level 1
  * CCC - level 2
    * xxx - level 3
    * yyy - level 3
  * DDD - level 2
    * zzz - level 3
    * vvv - level 3

I start from a menu with two option AAA and BBB. After I move the cursor over BBB the second-level menu appears with two other options CCC and DDD. So far OK. Now, when I quickly move the cursor over DDD the third-level sub menu does not show up, but when I move the cursor back to CCC the sub menu shows up, and when I go back to DDD then the sub menu also shows. Why it does not show at first time?

Have you ever encountered such a problem? I fixed the problem with MouseEnter and MouseLeave events, but I still wonder why it does not work properly without the events.

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
