DrawQuery results in grey-colored map

[Stefan Schwarzer]

Hi there,

must have changed something over the last couple of weeks that  
mapserver didn't liked...

When querying a country on my worldmap the country normally is  
highlighted in yellow and all other countries appear in the given  
classification color. But now all countries are colored in different  
grey tones, but still representing correctly the classes. It seems  
almost as if the PNG had been transformed into grayscale; but as the  
ocean still appears in blue, it's not the case.

Has anybody an idea what could cause that problem?

Thanks for any hints,

Stefan

PS: I am working with PostGres 8.1.0 & PostGIS, PHP Version 4.4.2,  
MapServer version 4.8.3
