Re: [Meshlab-devel] more bugs

thanks Marco,
   I tried using the windows release version, and tried different values of
the quality threshold in the quadric-texture filter, but it still crashed.
are you saying the values I enter for the quality threshold aren't

and yes, the other two issues don't seem to be related to the quadric
filter.
