Glad the 2 apps is correct. Is the "Thread is running ... etc." message normal when I have just opened the project, not yet run done any interactions (Run, Act, create object, etc.) and just opened the debug window? How do I use the debugger? How to set a breakpoint? All I see is the Debugger window with no contents other than the "Thread is running. Thread must be stopped to view details" message and the Halt and Terminate buttons enabled. Pressing Halt does nothing, and pressing Terminate closes and then re-opens the project window. Thanks!

Setting Breakpoints: In your code there is something like this:http://i1094.photobucket.com/albums/i442/kiavoldemort/Screenshot2011-11-28at61041AM.pngClicking on the side creates something that looks like this:http://i1094.photobucket.com/albums/i442/kiavoldemort/Screenshot2011-11-28at61423AM.pngThat stop sign is a break point. When your code runs, the debugger window will pop up.

Anyone have problems with the debugger sometimes showing contents and sometimes not? When have a break point and stepping through the code, it will sometimes remove showing the contents and sometimes show them, and recently I had trouble trying to get anything to ever show. Furthermore, sometimes the debugger doesn't show up at all, though the break point was stopped at. And Controls->Show Debugger doesn't do anything. For the visibility of the contents the debugger shows, To get them to show I usually try switching between the call sequence, or stepping once. But sometimes that doesn't work.

First of all - there's a bug with displaying multi-dimensional arrays in the debugger, which affects Greenfoot 2.1.2. It might prevent display of all variables if you happen to have a multi-dimensional array in scope. This will be fixed in the next Greenfoot version. If there's a separate problem, we'd appreciate it if you could find some definite sequence to reproduce it (even if you have to send us a copy of the scenario). You can send such information to support@greenfoot.org. Thanks!
