3.1D Upgrade problems

[Tom Russo]

We have recently installed the "maintenance tapes" to bring our IRIX up to
3.1D on 2 personal irises and a 4server8. Now 4sight seems to be broken in
a wierd way: Most of us here have user.ps files to remap keys, put up tools,
and fire up toolchests. Those of us who do have these things in our directories
now find that the tools and chests fail to come up one time in 3. The user.ps
files look like this:
---------here comes user.ps -----------

% User customization file.

% remap keys:
% caps lock (28420) mapped to control (left side) (28419)
% ~/` mapped to escape
% F1 mapped to ~`
% backspace mapped to delete
% delete mapped to backspace

--------that was user.ps --------------

Has anyone else experienced similar problems? Is there something obviously
stupid in the user.ps? Clearly, the problem is rooted in the user.ps file, 
since users without this file (most people use the same one as above) do
not have any problem with missing toolchests. We just can't see the problem.
Thanks...
