I donÂ't know the scripts in detail, but for succesful map clicking recognition (i.e. double-click + return), the exact number of markers placed in the editor must be given.
Did you change the number of markers in the editor? If yes, either place some dummy markers to match the original number, or scan the script(s) about some entry "EditorMarkers" or "InitialMarkers" and provide the correct number of markers.
Just a wild guess, but I hope it helps,
