Hi All, My setup is:
WinXP Python 2.5.1 TKinter version: $Revision: 50704 $ Tcl: 8.4 Debugger: WinPdb My program uses some Tkinter code written by someone else, that creates a basic 24x80 terminal across different platforms. The terminal worked fine in earlier versions of Python (version 1.5.2 and 2.2.1) but it's doing the weirdest stuff under 2.5.1 (so far I've only been testing in Windows XP). I've been playing with this problem for several days now and it's got me stumped. When I step through the code on the debugger it works just fine--but when I run the program without breakpoints *or* run it straight from Python the Tkinter module starts throwing exceptions. The weird part is, the exceptions occur in different parts of the Tkinter module at different times. I can run the program 5 times and no problem then I can have a dozen attempts where it never finishes printing the game introduction--and worse it stops at *different* points (and different parts of the Tkinter code) every time. There's no pattern I can see. I do nothing different each time, and the program crashes long before any user inputs. There are a few commonalities: 1) It's always Tkinter throwing the exceptions 2) Using WConio or a "glass tty" terminal there are never any problems. 3) As best I can determine, it seems to be some sort of timing issue. For example, one exception occurs in the "see" method because of a bad passed index. In the debugger I can see that the string "None" was passed--but the code doing the passing uses Tkinter.END! Worse, the debugger clearly shows that Tkinter.END should be "end", not "None" when evaluated right after the exception is thrown. I got a similar problem from the Pane.text.GetYX() function--it also returned "None" (randomly) instead of the coordinate pair it normally does. Has anybody ever heard of anything like this? I'm an experienced Python programmer, but I never deal with Tkinter and the randomness of this is really bizarre. Any help would be greatly appreciated!
