This is a strange issue, it has a workaround, but its still strange. The very short way to see it is to try to append an expression with spaces in it to a variable. Please take a look at the first text attachment for the demonstration of this issue. The second file contains my settings. in short, the bug is shown after doing env -i PATH=$PATH zsh -f Please email me directly. Thank you. -jason kim ____________________________________________________________________________________ Need a vacation? Get great deals to amazing places on Yahoo! Travel. http://travel.yahoo.com/
