Whenever I detach my remote "screen" session and ctrl a-c a new window, it opens the new window with "/" as the PWD. Another extremely annoying problem is that whenever the "screen" session is detached, the IRSSI IRC client cannot find the log files to write into them. It mostly happens with private messages.
This only happens when the "screen" is detached and goes away when I attach again.
The remote computer is running Ubuntu 10.10.
