Hi!

Browse button does not work. Thanks for bug report. I'll check the problem.

If you enter path manually and set the checkbox wsjtx starts when remote mode is selected (I tested this). You can find wsjtx path with console command:

whereis wsjtx

How ever I do not recommend starting wsjtx (or fldigi) when remote is selected. Reason is that if cqrlog dies (it does that very seldom with version 2.x.x, but usually in the middle of qso by Murphys law) then it will take down also wsjtx (or fldigi) because it is running as child thread of cqrlog.
If wsjtx (or fldigi) is started manually, as it's own thread, it will stay on running and qso can be ended. Then start cqrlog again, select remote and finish logging.
