While going on stuff and 30 mintues later, I set up Runescape, and ten it just shows White screen? how can I prevent this and why does it always come?

Are you saying that you bring up a RS screen and then browse some other thigns and then come back or that you are just doing random things for 30 minutes and then opening a new window and loading RS?

 

 

 

If it's the first, I've had the same problem before and it can only be avoided by not browsing other tabs while RS is loading/running.

 

 

 

If it's the second, again, try not to switch tabs while RS is loading/running and, if you're not doing anything while it's loading/running and still getting a white screen, then I don't know what to say.

What browser are you using?

 

 

 

If it's internet explorer then try opera or firefox

Im using Firefox.

Okay, then can you define the problem more clearly, is it like what acenator said?

Sometimes when I climb SOS stairs or have random event, it happenss, when I click Tip.It then switch to RS it happens, or when I go on few sites and then load up RS.

Uninstall java and then reinstall it. Delete the jagex cache that is found at c:>windows>jagex_cache_32. If that doesn't work then try using opera instead of firefox.
