DSCConnection: From now on a SV will only be created if the error before was -1950679035 (SV not found). All other errors will be returned to the user.

Included OnlyConnect? Control in Connect Core.vis, necessary if the last PV of an actor has no URL defined.

Corrected small bug in the UpdateFirst function of the DSCMonitor: Now it should work for all variables and not just for one.

Corrected problems in the Connect Core.vi which could lead to unnecessary commits of already existing shared variables. In fact, the last version was just not working properly.

Modify custom event registration in CS++GUIActor. (An already configured event refnum can not be modified later in oder to add more custom events.)

Repair Do.vi. It was broken, wrong wiring, for unkown reason.
