A little bit of RadMenu feedback for you....
1) I know you said don't comment about the documentation but... Is RadMenu in the Toolbar the same thing that is RadMenuStrip in the documentation! Just want to make sure I'm testing the right thing. :)
2) Designing the Menu seems counterintuitive. I couldn't figure out an easy way in the form view to manipulate the entries that were created. Whether I was creating a top level menu or a sub level menu item was unclear. I created a brand new project, dragged the menu control on and typed &File in the space. Next I typed E&xit in the space that appeared below File. It appeared to the right of File. I typed &Help in the space (still below File) and it appeared below File.
3) Dragging the RadMenu on the form does not add all the references that you need to use the control. I had to add the reference to Telerik.WinControls from the examples folder. Should there not be a common bin folder?
4) It seems that clicking on one of the menu items and pressing direction arrow keys and then changing the focus causes Visual Studio to crash.
