An easy way to see the effect is to open gedit (or some graphical text editor) and move the mouse over the empty document. Most of the area will show the cursor as a the "crossed capital letter I" (i.e. a T also crossed underneath), except in these "dead spots" the cursor reverts to the mouse pointer. As mentioned in the OP nothing useful can be done with mouse interaction while the mouse is in this area.
One exception to the rule that this dead spot applies to all applications is Tilda, a drop down console (quake-like), which I can easily imagine has different drawing and capture rules. Stock Ubuntu 11.04 install on a Dell mini 10.
