I think he's very busy.

Now I'm getting confused because my hello world program can indeed print 
a 100 chars line BUT only until I execute other programs in that console.

Example:

start--run--cmd
mode con cols=100			<- OK: 100 cols console
helloworld				<- OK: no width change
rhide					<- auto full screen change
(exit rhide)
(alt-enter)				<- return to graphic window
mode con cols=100			<- OK: 100 cols console	
helloworld				<- FAIL: 80 cols while running

from now I cannot get 100 cols during execution of helloworld in this 
console, thought I do can with a new one.

I get this same problem using another exe in place of rhide. This 
another program is a big exe built with DJGPP. I have tried inserting a 
printf at main() and exiting, but I get the same behaviour.

I have tried some other EXEs, like du or upx between but these work ok, 
using the 100 cols console.

Any idea?
