Description Jiri Sedlacek 2007-08-20 10:27:03 UTC 
Open the IDE, create new AnagramGame, start memory profiling with default settings and try to take snapshot as soon as 
the Take Snapshot gets enabled:

Comment 1 Alexander Kouznetsov 2007-08-22 12:34:21 UTC 
I got an NPE on Take Snapshot button click after played with the profiled AnagramGame application so "as soon as 
the Take Snapshot gets enabled" note doesn't seem to be obligatory.
Comment 2 J Bachorik 2007-08-31 14:39:53 UTC 
this is fixed in Dev Build 20070831
the "Take Snapshot" button is now correctly enabled/disabled thus preventing user trying to take snapshot in an
inappropriate time
