It seems that sometimes the context menu is drawn at a location such that one of the menu selections is underneath the cursor. Just a little, but that's all it takes.

I can reproduce this easily by displaying a page of thumbnail results from Google Advanced image search (http://images.google.com/advanced_image_search?hl=en). Go full screen, change the zoom level and right-click on different thumbnails. Normally the context menu is drawn above, below, left, or right of the cursor so that the context menu is completely contained inside the screen draw area, and no part of the menu is directly underneath the cursor. But it's not hard to find one of the thumbnails for which the context menu is drawn just a few pixels too close to the cursor, so that one of the menu items is under the cursor. Release the mouse and you've activated that menu item. One you've found a thumbnail positioned just right, the problem is 100% reproducible.
