I'm trying to use MTR for my Holux M-241, which seems to work well, except for downloading the log data: After some activity (two popups with progress-bars) I ended up with an empty Data Log List each time.
This might happen if you don't have the GPS connected using an USB cable. Data download through BlueTooth doesn't work.
I enabled "log to file" but don't have any clue where to look for the logfile . . .
Just search your hard drive for Travel
and you'll find it.
