Scripting

If my app run on Webplayer version 2.5, it works well. But i upgrade Webplayer to 2.6, WWW component don’t work well, sometimes it works, sometimes, it don’t works! Any answer?

the thread priority is set too low, so on heavier cpu use, the www loading basically dries out cpu time wise

I try use this
Application.backgroundLoadingPriority = ThreadPriority.Normal;
www.threadPriority = ThreadPriority.Normal;
This problem go on!
