Tool Strip memory leak

[Nalin]

I was facing memory leak in one of our software. I read about ToolStrip memory leak here and that was my problem also. I The profiler was showing "UserPrefereneChangedEventHandler" in my root path.
So, i added code to get rid of that by unregistering all the events but still I am having memory leak because of ToolStrip.
- Some of the objects of ToolStripmenuItem are Disposed but not removed and some are not even disposed.
Now i am not able to see any event in the root path, when i run the profiler.

What can i do to find out the root cause of memory leak.

Shall i attach snapshots of my root paths here?

The root paths of the ToolStripMenuItem instances will provide information about why they are not garbage collected. If you attach the root path and preferably an allocation call stack, I can take a look at it and hopefully provide some hints about why instances are not GCed.
