Sorry to burst your bubble but that has NOTHING to do with the disconnects when it's just GB2 related. All that does is set more of your bandwidth to wow...
Actually raising the priority of a process tells windows to open more resources to that program, namely your CPU. This issue is affecting at least questbot as well as GB2 and I havnt had to sign back into wow since I did the above. No need being a negative Nancy when someone puts forth a possible solution, even if you dont agree.
