Does it run on WIN11 I'm having trouble viewing my log file. Is there a help page?

It has been tested and used in Windows 11.  What exactly is the trouble?  Aren't you seeing any files?  aren't you seeing any telemetry fields?  Aren't you seeing a graph?

I am working on a short manual, I will be uploading it here soon.

I can see the files in left, I can click and highlight the file I want, but nothing happens. I can see a "ready to begin" but this is a dead link? How do load log files in?

You have to select which telemetry channels you want to see in the graph, by ticking the boxes next to them, in the middle pane

Reading the previous comments from cncworkbench,  I have the same issues. After clicking all the checkmarks you want to see, Alt, Air speed, gps, I clicked on Map Flight Path and nothing happens 

Can you share thirst few lines of the log file here?  Is it a .csv file from a Frsky radio with Ethos?
