The first few times that I used K-Meleon to play the game called Mobsters (by: Playdom) on myspace it worked great on doing the missions.
After either the fact it required the flash player to be installed or after spending my favor points K-Meleon stopped displaying the script the way it should. It was not showing the certain places to do missions such as Downtown, Out of town etc.. Also it was duplicating missions on the same page. Any help would be appreciated.
