It has been a while since I used my DCS-5300. Yesterday I connected to my computer and updated the firmware and it worked fine. Today I went to access it and it asked to download the VapgDecoder. I have seen the other message about active x controls before but I do not remember this one. It apparently will not load without it. Is this common and safe to use? I saw some info about stack overflow problems with it. Thanks. Garner
