This release - makes the Propagation window resizable and provides a Maximize control in its upper-right corner (tnx to Nuno CT2IRY and Joe W4TV) - at the top of the Propagation window, provides separate "Analyze DX in the Spot Database Display" and "Filter and analyze DX active during past 24 hours" functions, replacing the Update button previously located at the bottom of the Propagation window - displays the Propagation window and invokes the "Analyze DX in Spot Database Display" function when you click the Main window's Prop button - if the "Filter and analyze DX active during past 24 hours" function is invoked with no "Maximum distance" specified, sets the "Maximum distance" box to 500 (tnx to Joe W4TV) - when checking a spotting callsign to see if it's listed in the Special Callsign list as a bad source, remove any appended SSID (tnx to Iain N6ML and Joe W4TV) Notes: 1. If the Propagation window is displayed on a monitor whose vertical resolution is less than ~900 pixels, SpotCollector 6.4.8 will automatically reduce the height of the Propagation window to 95% of the height of your monitor; you can further reduce the Propagation window's height by dragging its bottom border upwards. 2. The Propagation window's vertical scrollbar cannot be controlled with a wheeled mouse (addressing this is on SpotCollector's enhancement list) - updates the ConfigurationSpecialCallsigns.htm, and SpotDatabase.htm documentation files SpotCollector 6.4.8 is available via the DXLab Launcher, and via 73, Dave, AA6YQ
