hi,
thanks for the investigation.
right now i can work around it easily ( i was simply testing the case
that the user submits an "empty" form. so instead of just submitting
what i get, i will manually set the textareas to '' (empty string). no
problem for now)..
but maybe a known-bugs webpage would be a good idea for now, so that
other will know that this is happening...
thanks,
gabor
