XV6700 won't run 2 apps at once

[Scing]

Hey guys. My XV6700 won't run 2 applications at once, appears to be if they both require network usage.

I can start up Skype, and it will stay on just fine, but if I open IE then it shuts Skype off. This is QUITE troublesome to say the least, because Skype is one of those things I want to have on 24/7. I've looked through the options and can't find what could be causing this? I'm running OS 5.1.478, Helmi's 3.5 Kitchen.

Thanks!

Reflashed original VZW rom on, going to WM6. WM5 was causing me too much grief with slowdowns and what with certain applications when there was over 20mb free to run programs with.
