The wireless dongle is plugged into the front of teh computer (not a usb hub) and I just re-installed the driver from the manufacturer website - still have the problem. The wireless dongle has an "activity light" on it - when it flashes, it works fine , when it is solid "ON", it does not work (picture freezes). When the issue presents itself, the "activity light" goes solid, but when i stop then start iCamSource, it resets and goes to flashing - hope that made some sense.
