problems playing

when I play ROTMG on chrome, it runs fine, but when I go into a .swf or play on opera, I start having problems:
While at nexus, if I do anything for about 20 seconds, I d/c. I dont know why this happens, and some parts of the map are black, and I can't walk there, like if that place hasn't loaded yet... What is happening?

You shouldn't be playing through a browser anyway.

Use flash projector, it is much better.

if you don't know, .swf files are played throught flash projector.
