I feel this problem is too large for a quick comment, which may or may not be read: Sonny 2 makes my browser crash. I tried it on both Firefox and Google Chrome. So far, it's only happened in battles, seemingly randomly. The errors aren't very descriptive, just "The Flash shockwave has stopped working." with a sad puzzle piece.
Finally, someone having the same problem. Yes, the game only crashes and restarts IE/Firefox when you're in battle mod. I had the exact same problem with Sonny 1 and could not fix it. It's the result of Flash10a.ocx screwing stuff up.
Does anyone have any experience fixing this problem. Is is the only game I've ever played with this error.
