Bob: if you are still using this command line argument Command Arguments : -steam -applaunch 320 -dev -allowdebug -windowed -game "d:\games\valve\steam\steamapps\SourceMods\HLMod" +map "sdk_3d_skybox"
and starting up the hl2.exe try changing the arguments to something like -dev -allowdebug -windowed -game "d:\games\valve\steam\steamapps\SourceMods\HLMod" +map "sdk_3d_skybox" Since you are already opening HL2 I don't think you need the steam apps arguments, well my VS .Net debugs quite happly without them. _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlcoders
