In case you haven't noticed, you can't play BattleTale while changing tabs. The problem lies with Flash and it's sleep feature, when you change tabs, the framerate cuts down to about 2 frames per second, causing issues for the games calculate framerate.
There is a setting you can edit to fix this:
Locate your "mms.cfg" inside your Windows folder. 32 bit computers: C:WINDOWSsystem32MacromedFlash 64 bit computers: C:WINDOWSSysWow64MacromedFlash
Open mms.cfg in notepad, and find the following line: FullFramerateWhenInvisible=True
Set it to FullFramerateWhenInvisible=False
Copy and paste the line if you can't find it in your mms.cfg.
Save and restart your browser. You should be able to play BattleTale while changing tabs now.
