[mapserver-users] Mapscript Strange behaviour of drawQuery

[Thomasch]

Hi,
I'm using Mapserver 5.2.1 on WinXP.
If I try to draw a query using drawQuery() the scale of my map is 
changed - even if the qurery returns no result. If I don't draw the 
query, everyting is fine.

Please see my code in Attachement.

Is there a workaraund?


Thank you
