Hello Cesar,

This is caused by a bug in recent versions of CommandShell (thanks to Don
McLane <dmclane at u.washington.edu> for finding the problem).

As a work-around, please try loading the OSProcess package first, then load
CommandShell. This will allow CommandShell to work properly.

Also, if you are using SqueakMap to load CommandShell, try doing "update map
from the net" in your SqueakMap package loader. The most recently published
version of CommandShell is 4.2.3.


p.s. The fix for this bug is in SqueakSource at http://www.squeaksource.com/CommandShell,
but I have not "officially" released it as CommandShell 4.2.4, so maybe I should
do that now ;)
