Re: [MACTCL] Setting environment vars from tcl

[Jim I. <ji...@ap...>]

James,

I did notice this when I was playing around just yesterday.  It is odd, 
because it mostly works just fine, and then every so often you will get 
the "can't read..." error, or it will just silently fail to set the 
environment.  Then one or two commands later it will work again.  Please 
file a bug on this, and if you want to have a whack at it, that would be 
great.  It is a pretty annoying bug.

Jim
