Dialog causes Crash

[Binder]

I have a problem with my first Dialog Script.

Here is the code:
SASCHA: Hallo
PATRIC: Ja was ist?
SASCHA: Wollen wir was spielen?
PATRIC: N E I N
SASCHA: Okay tschöööööö
stop

After this Dialog the Game crash and exit to AGS.
What did i wrong?

does the special "o" character in the second to last line work? or is that what causes the crash?

Is there any pop up window spouting a bunch of numbers and letters?  If we could get that, we could identify the problem, and when I say "we" i mean Chris can.

If you're using SCI fonts for speech and those "o with dots on it" (i cant type in these characters here) are using ASCII #>127 then it's most likely to crash the game, as displaying characters with ASCII code>127 with SCI fonts is not supported.

I changed the german ö to oe but the game crashs again:

An error has occured. Please contact the game author for support, as this problem is caused by the game rather than the interpreter

Error: DoDialog: all options have been turned off

Are the dialog options all off, like the error message says?
