I have this annoying problem with my add-ins. Even though I have PDM set to load on start-up, and to force log-in, while I am using SW my PDM add-in will "disconnect" itself. This requires me to have to go to:

Tools menu ->Add-ins ->deselect the check box for PDM, then repeat this process so I can re-add my add-in, and relog-in to our PDM client. (Is that confusing enough or what?)

Is there a reason for this behaviour? This might happen once or twice a day.
