Hello, is there a possibility with a selfprovided Map dialogue to switch off the blue markers? With the GPS these aren't visible. This dialogue runs on a Dedi server, the client "Extended map info" - option don't produce there the desired result. I have looked in ui.pbo and ca.pbo for the "GPS dialogue", up to now, unfortunately, I haven't made a find... I am grateful for all tips or proposals Mfg Langer p.s. thx to BierAIG Falke_Maik for translation
