st: bad update? can't set level for weighted tabs

[Graham Wright <gwwri@brandeis.edu>]

First off, we're in version 11.1

So we all admit that this is valid syntax

svyset [pweight=wt3]
svy: tab vara varb, ci level(80)

right?

It does a weighted tab of two vars and gives you confidence intervals, 
but at the 80% level instead of 95. I've used code like this all the 
time because we did a study where we reported everything at 80% cis for 
random reasons.

This syntax works on my computer, and on MOST of my coworker's computer, 
but for one of us, it doesn't work...it used to, but it doesn't now. It 
generates an error message "option level() not allowed."  The strange 
thing is that he has multiple version of stata (one on his work computer 
and one on his laptop) and it dosen't work on EITHER of them, but works 
on mine, and another 2 coworkers' computers. The only thing that I can 
think of that's different about him is that he has actually updated, and 
is running the sept 30th update, whereas the rest of us are lazy and 
haven't updated since July.  Now I'm scared to update, since I don't 
want this to start happening to me, and I don't know if it's possible to 
un-update.

fun stuff:
-this only dosen't work on weighted tabs, the following code: "svy:reg 
vara varb, level(80)"  works fine
-if you type svy: tab vara varb, ci l(80) you get the same message 
(option level() not found) so stata recognizes the command, just doesn't 
think it's a valid option for tab.

So my question is

1) does anyone else have this problem?
2) does this seem to be due to a buggy update?
3) If so, a) can someone tell stata about this? b) is there a way to 
rollback updated to a previous version?
