hi there
is this at all related to the problem i was experiencing here (my
problem is announced in blue after the intial pits claim): http://
pmwiki.org/wiki/PITS/01098 ?
we discovered it wasn't fox, but a pmwiki problem - but i'm using
fox, so maybe now fox will do the internal maintenance that pmwiki
should be doing?
just checking
thx
adam
