#2 XLogo does not run on a german system

[Euklid]

Double clicking the XLogo icon starts XLogo normally.
But then entering any command and pressing the GO button results in a
sound only but nothing happens.
No commands are ever executed!

The console says:
2006-06-06 10:56:52.165 XLogo[445] *** -[NSScrollView clearAllText]:
selector not recognized [self = 0x3ad810]

I know: It is not localized to German yet. But still it should run (in English).

Switching the language to English and restarting XLogo makes everything
run perfect. I tested this on 3 different models (computers) all running OS
X Tiger 10.4.6.
