I've got to look into this. Not a termcap problem. A terminal problem rather. This "storing title on a stack" stuff is something very few terminals support. Recent xterms does, but few if any others. Other terminals will at best have sequences for "set title" and "read current title". -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
