[Pharo-project] cmd-dot is being temperamental in 2.0

Hi - on a fresh Pharo 2.0 image (build 20041) open Nautilius and press cmd-dot: the usual User Interrupt debugger will appear. Close the debugger and click one of the Nautilius packages and press cmd-dot: nothing happens. Open a new Change Sorter window, go back to the previous Nautilius browser and cmd-dot works again. This is on Mac running OSX 10.6.8. The issue is reported in: http://code.google.com/p/pharo/issues/detail?id=5766 - Francisco
