I'm having this same issue running MapGuide Server (Version It
looks as though this issue has been resolved (for future a future release
?). I'm new to this community so I don't know how this works, but there is a
service ticket for what looks like the same issue...


What does this mean for me? Do I have to wait for the next release or is
there a fix out there somewhere?
