Problem with W7 and simple MessageBox

Hello.

i found a small problem with the messagebox cmd.

I have written a small program which should show a detailed error message. Now the problem is, on one PC it works, on the second pc i get an error message. On this pc i alst get an error message if i try t run the script within scite.

Here's the code:


msgbox(1, "Falsche Anzahl Parameter", "Es muessen exakt 3 Parameter angegeben werden:" & @CRLF & "  - Name der gepackten Datei (z.B. 7-Zip.rar)" & @CRLF & "  - Zielpfad (z.B. 7-Zip)" @CRLF & "  - Pfad von Uniextract.exe relativ zur Ketarin.exe (z.B. Apps\Uniextract)" & @CRLF & "Das Programm wird beendet")


and here's the status message from scite:

G:\_Notfallstick\Neue_Struktur\Apps Essential\Eigenentwicklung\Quellcodes\UniExtract.AU3 (4) : ==> Error in expression.:
msgbox(1, "Falsche Anzahl Parameter", "Es muessen exakt 3 Parameter angegeben werden:" & @CRLF & "  - Name der gepackten Datei (z.B. 7-Zip.rar)" & @CRLF & "  - Zielpfad (z.B. 7-Zip)" @CRLF & "  - Pfad von Uniextract.exe relativ zur Ketarin.exe (z.B. Apps\Uniextract)" & @CRLF & "Das Programm wird beendet")
msgbox(1, "Falsche Anzahl Parameter", ^ ERROR

the only difference between both systems what could cause this is that the errorous system is set to 150% in the display settings. Could anybody confirm this problem?

Thanks,
Tom
