@Frontier - Do you have the devel enabled?

I am facing a problem with battery drain after playing webos games started from icons in menu. I have catorise installed and created menu items for all the webos games. If I launch from shell, then there is no problem but if I run from the menu, even after exiting some process keeps running consuming about 20% cpu continuously which drains the battery (I checked this using BatteryGraph app).
Also this happens randomly.
Any ideas/solutions?
