Update: This does not just happen with games, it can happen with other Flash content on the page as well.

I have been testing hundreds (yes) of Flash games and it did not occur to me that they could cause problems with battery life and performance- besides the obvious impact when playing them, of course.

An example is the game "Afterglow". It is a game that loads, but does not get past the menu screen. I closed the game, but it was still resident in memory and draining the battery. The app is so agressive it activated the device even after being locked.

If you play a Flash game but then notice your device is laggy or running warm, it may be due to a Flash game still running even after closing the browser. It will show as "browsersd" and may be active when you show no open tasks. Need to go to terminal and check from there and then reboot the device if present. Audiopulse may also be running too. The combination of both has been up to 90% of cpu and 40% of memory used. UDPATE: Posts below details how to also kill em' without a reboot.

The N900 needs a task killer for this. It is fine to call this a mini-computer- but at least give me the same function to till kill tasks. When this happens with a computer, you can kill the task with ctrl-alt-delete and then find the culprit and kill it. A UI that covers this process would be good.

This has kind of sucked the fun out of playing Flash games for me, since Afterglow is not the only game that does this and it can get old to have to check after running each game.
