My code looks quiet exactly like your one, there are
just more then one of your function "get_inchar();"
running at the same time, because there are more then
one textbox I can write in. And then, it crashes.
BUT I went out, it works, when I put a wait(1);
BEFORE the inchar. I just don't know why. XD

So, this code crashes:

Click to reveal..
Code:
function inchar_fu()
{
while(1)
{if(inkey_active!=0)
inkey_active=0;

inchar(my_str);
wait(1);}}

function main()
{inchar_fu();
inchar_fu();
inchar_fu();}

And this does not:
Click to reveal..
Code:
function inchar_fu()
{
while(1)
{if(inkey_active!=0)
inkey_active=0;
wait(1);
inchar(my_str);
wait(1);}}

function main()
{inchar_fu();
inchar_fu();
inchar_fu();}

I invented this code, because I haven't my real test-code
on this Netbook, but it should be the same...

Jea, but it works and I'm happy. grin
Thank you EvilSOB for your help. ^-^
