Surpress Dialog in Script

Question

Hello everybody,
I have a little issue with photoshop cs scripting.
I generated a script with scriptlistener and costumized it for my needs (arguments). When I'm running the script (it does a conditional mode change) everthing works fine but at the end of the conversion a dialog pops up and says something like (sorry I have to translate from german)
The title of the window: Grayscale (Graustufen)
Label: Scale (Größenverhältnis)
a textbox and a OK button.
How to surpress this dialog?
It occous when I convert mode:bitmap to mode:rgb
I attached my script.
Thanks in advandce.
Best regards
Moritz

I didn't include the conversion to grayscale. when im converting manually it works fine but the windows comes up. I'll try to convert to grayscale first and then to rgb and post the results here.
Hum, because my script is not yet available i'll post the relevant parts here. I hope this is ok.
