Using Windows 7 pro 64 bit. Hp pro book 6455b. Studio live 24.4.2. Firmware 1.0 and build 195. Driver version 126.96.36.19957. Used the laptop FireWire connection and then tried the star tech 1394a card EC13942. Also tried a hp pro book 6550b. When connected, cannot scroll screen side to side and sometimes locks up. Can still operate with iPad though. Disconnect FireWire cable and program closes. Plug cable back in and the program pops back up and works fine. Sometimes after a while it will do it again. Sometimes will work for the rest of the show.
