One thing i have noticed on my computer is that open a client, play, stop log off. The nthe next day i login in have plenty of problems. I look at my task manager and there are multiple clients "running". I guess that sometimes my clients do not actually close. So suggest b4 you log in check you task manager to make sure no other clients are running. Thats all I guess, might work might be happening to you, not sure, but worth a try.
Good Luck
