Just for fun and grins, on my Windows 7 desktop that doesn't work properly with Webtranceiver, I launched Oracle's VM Virtual Box and opened a virtual machine running Linux Mint version 12. Opened Firefox under Linux , logged into my Allstar Node and instantly got the audio feedback saying I was connected. I then logged in with my node password and got audio confirmation that I was logged in. I can enter macro commands to change frequencies and that works ok BUT the PTT button doesn't key the transmitter. 90% there in having a working node from the new PC even if I'm having to use a virtual machine to do it. The virtual machine passes all I/O down to the Windows system resources then out to the network to control my node which leads me to wonder if it isn't some issue between various browsers and the java code in webtranceiver? I've tried Firefox, Internet Explorer, Opera, Google Chrome and even Safari. Being a little more methodical today, it appears that all of the browsers under Win7 will actually log in to the node. The macros change frequencies and other parameters ok, you just don't get any audio either from the radio or system acknowledging you logged in, nor do you hear audio from the radio even if you unsquelch it. The PTT does not work under any browser on my new PC. What might be a clue is that under Linux, it is probably using a different version of the Java interpreter, at least the audio passes under that version although the transmit button (PTT) does not. Wonder if anyone has Windows 7 professional version that does XP emulation and try running a browser under that and see if webtranceiver will work under xp emulation? I have the home version and can't see laying out another 80 to upgrade to the pro version just to get XP emulation. Wayne W6IZK node 28146
