[Tutor] crash - switching between text window and graphics/gamewindow (high score)

[D. Hartley]

The play file does end in ".py".  I am running it on Windows.  You can
double-click the play file, and run it straight that way, which is
when the crash occurs.  If you right click the file, go to "edit in
IDLE", and hit F5 to run it, the crash does NOT happen. I'm not sure
why (but this is also why my debugging program won't tell me what's
wrong).

In fact, I wish the debugger *would* give me something, because then
I'd have a specific error, which would make researching the program on
google or in forum archives much easier! At the moment, I'm getting
nothing (or too much information about unrelated problems).

Thanks for any suggestions!

Hey

I'm curious

What extension are you using on your game???????????
is it .py???????????????

And what OS are you running the game???????????????

Another thing. I made a space ship game to learn Python. Is there a
possibility that we exchange the games so we can know differents points of
view????????

I'll wait your reply

Regards

Alberto
