I used to be able to download track files from my powerflarm rectangular
butterfly display by inserting a usb, pressing the button and then pressing
again on the "flarm" status and again on "log download" without turning the
unit off. It no longer does this now I have to power off the unit insert a
usb and power back on and wait. Its not a lot longer but it was convenient
to do it while still up and running. Any one else noticed this?

Yup, saw that in my brief trip to the Seniors.
Unfortunately, seems to be that Butterfly doesn't play well with latest
FLARM protocol update. And Butterfly is an "old unsupported product"...
I'll ping the Butterfly guys again to see if there's any way to get this
fixed. Until then, just power-cycle your panel to trigger the IGC file dump.

Hope that helps,
See ya, Dave YO
