Jea, this code above was just an example to show you what I mean, in my code all textboxes have a loop in it like:

while(Wait while I'm not active)wait(1);

There is just a collision with two inputs once, when I
"switch" to another textbox. Was it that, what you meant?

If not, I though my script for the contribution-forum,
so there is no problem with writing my project in here.
It's just a very big script, and I don't want to vaste to much of your time...

But if you can have a look on it, it'd be very nice. ^^
Here's the zip with the whole project:

(sorry about ifile, I'm not at home and cant upload it on my server...
If I shall upload it on rapidshare or other platforms, just say)

Erm... Jea, the Commands etc. are on german, I couldn't translate it jet.
Hope that's no problem.
It's at least formatted to some degree and quite neat.

Thanks
