I am having similar problems. Cannot detect GPS on either Firefox or IE (32 bit, 64 bit, whatever). Sometimes, after multiple installs of drivers and plugins I can get it to work, but then after a couple of days it stops working. I also cannot "see" my GPS on my computer, which blows the idea of downloading pocket queries. It shows up under Other Devices, like a printer, but not as a drive that something can be copied to. I would love some ideas here.
