Glad to hear it. Thanks to Glynn for the suggested fix.

Michael et al,
I'm happy to inform that I just compiled Grass from the latest svn and
the problem is gone. Map canvas works with both Polyconic American
projection and lat Long projection...
Cheers and happy new year!

Thanks! I will gladly test the fix as soon as my r.watershed process
finishes. It's been running for 1 day and will probably take 2
more to
end... my laptop is almost melting...
Thanks again
Daniel

I've committed the fix below suggested by Glynn. I tested it on
the new NC
demo data set and it causes no problems.
Of course, the old regexp statement worked too in my tests. Since
I'm so
abysmal at regexp, I just have to go with this, like I did with
the old
statement (someone else suggested it to fix an earlier problem
with latlon
regions).
Could someone please test this since I'm not completely clear
what breaks
the old algorithm that works with this one? Hopefully this will
work with
all projections this time.

Probably related to this in mapcanvas.tcl:
# Finally put this into wind file format to use with
GRASS_REGION
regexp -nocase {^.* (\(.*\))} $parts(projection)
trash end
set parts(projection) [string trim $parts
(projection) $end]
The "*" operator will try to match as much as possble, so
matching the
string "99 (Polyconic (American))" against the regexp"^.* (\(.*\))"
will result in the ".*" matching ""99 (Polyconic " and the "(\(.*
\))"
matching "(American))", so "end" will be set to "American)"
Also, using "string trim" here is bogus; it discards any leading or
trailing section consisting of characters in the specified string,
which may be more than just the string itself (if $end contains the
digit 9, it will strip the projection code).
It should probably just match the portion that it wants, e.g.:
regexp -nocase {^([0-9]+)} $parts(projection) trash
parts(projection)
rather than trying to match and discard the portion that it doesn't
want.
