Robert, I notice that in the context menu for the map, the mouse cursor disappears for me when I enter the context menu. I have the same problem in my context menus and am wondering if you have done any looking into this. I did a little test and I see that it may be related to the hand cursor used for the map.
Here was my test: I simply right-click on the map. My cursor disappears. I then activated the draw widget, which changes the cursor to a pointer. I then right-clicked on the map rather than starting to draw something and the cursor did not go away. Also, I get an error when I attempt to draw anything using the draw widget. The error says it is in the drawEnd function. This is the same in both configurations. I am using IE 7.0.5730.13.
