Sorry Mohamed this doesn`t help me at all.
There are 8 diffrent outlet types in my map, each of which has its own pushpin colour. All I can do is right klick on em ('format legend') or double click on a pushpin in legend and then I can change colour of each pushpin type in ´the range window......don`t know what you mean by sets.....and the main problem still is how to make map point accept that 'hide bmp' as transparent colour..please read through my problems with paint as editor as well.............
