Hi Dave,
I do not give up easily. I re-copied the gauges across from PF3 and TGS.gau now works! Don't ask me why, the files were of identical size. So I have a working TGS gauge so could stop there.
But . . . may I ask the difference between TGS2.dll and TGS2.gau? The look identical in terms of file size and function. Maybe having both there is causing a clash because panel.cfg does not specify file suffices? Which should I use?
Best regards,
John
