Comment 11 for bug 573041

There is no bug in the ubuntu 64B
But effectively the bug exists in Lubuntu Xubuntu and ubuntu 10.04

It is very easy tou correct.
In a terminal you can with sudi gedit create the file 90-dosemu.conf

Or woth sudao nautilus you can save the attached file in the directory
/etc/sysctl.d/90_dosemu.conf
And it will works marvelous.
The same problem exist for win.
