I do believe that data from the console/display continues to be received by the Heavyweather Pro program even when it's not the top window on the PC. The way I'm setup I have HW Pro displayed on my wx PC and the "PC" letters shown on the console/display until some other program pops up it's screen over HW Pro. It is then HW Pro appears to have stopped updating when it's actually still doing it's job, just not displaying updates while in the background. While it's in this state I can go online with another PC and look at WU, CWOP, PWS, etc. and still see the uploads arriving. Once you go back into the wx PC and click on the HW Pro window to bring it back on top then it's starts showing updates and the PC letters on the console reappear. The connection never really dropped. At least that's the way things run here.
