With the change to 6.1, the behavior of screenconnect changed. The default ActiveX-plugin (ClickRunOnce or ClickOnceDirect) gets no longer used, but instead the full fledged client gets downloaded/installed (this requires admin privileges, which our users do NOT have on their computers). To be quite frank, this change makes screenconnect basically not usable to us anymore (not needing admin privileges was on of the reasons we bought this product).
Please revert back to the default behavior from 6.0 and previous versions.
