I have installed a brand new ZoomBrowser EX v 5.7 supplied with my new G7 and the CameraWindow does not open. It flashes and disappears. ZB does not communicate with the cameras – I tried G7 and S50. Both cameras are perfectly recognized by the PCs. I upgraded to ZoomBrowser EX v 5.8a and still have the same problem. I have tried the software on two different WIN XP SP2 PCs and the effect is the same – no Camera Window. When using the ZB EX v 4.6 I have no problems whatsoever. Any suggestions how to make CameraWindow in Zoom Browser EX v 5.7 or 5.8 working ?
