I was just giving V6.0.8 a try out - looks quite impressive...
One bugette though - I had beaconing turned on and decided to put out a CQ. The slot selection dialogue box opened, I selected a potential slot and hit the "sniff" button to find out if it was clear - a second later, the beacon timer expired and my radio put out a beacon - on the slot that I was sniffing!. It probably should inhibit beacon transmission while the dialog box is open - or switch back to the calling slot for the transmission!
Thanks for reporting.
Bug is not fixed and will be released in V6.1.
Beacon will be put in "Paused mode" in case you are currently sniffing a frequency.
