This often happens if there is no data, so this is one thing you should check for. All my reports work as follows (done through some generic report classes in my case):

select ...
  from ...
  where ...
  into cursor Tmp
if _tally = 0
  MessageBox("No data - perhaps you should check your criteria.")
else
  report form ...
endif

Move it to the server though and the preview does not show up. I can tell that "something" happens because I have a bunch of WAIT WINDOWs that fly by as it is doing a wack of calculations.
