When I experienced/resolved this problem on my own a while back, I figured it was a fluke. Today I discovered 3 other campus users who've been enduring the bug, so if anybody else is still putting up with it, here's your solution:
If you're using Dreamweaver 8 and it keeps forgetting your connection information, forcing you to re-enter your login and password every time you use it, update to 8.0.2 and that should fix it.
