For people getting their Bridge program doing random disconnects from your device as well as freezing on your dev, I found the solution. I might be wrong, but I've had my device connected for over 3 hours now without disconnecting. No more headaches and worrying about whether or not it was written correctly. I shouldn't have even THOUGHT that 
All you need to do is put your device in USB debug mode, on other words, NOT Kies mode. And make sure you're connected to some sort of network so your device acquires an IP address or else you won't be able to connect, because as I'm sure you know, Basic4Android Bridge Connect dialog box asks for an IP address, right? So that's my solution. You'll find that in your menu/Applications settings. That's about it.
Both the Designer AND the coder have remained connected now, no disconnects at all.
