John,
I reduced the number of macros to less than 127. It seems that once the number exceeds 127 FSUIPC will no longer update the [MacroFiles] entry in the .ini even if the number of macros is reduced to the 127 limit. I had to, once again, delete the [MacroFiles] entry and let FSUIPC rebuild the entry. It's all working fine now except that I have to reassign all of my buttons and switches.
If I remember correctly, when I first started using macros so many years ago there was a limit of one macro per macro file. The fact that I can put many macros in any given file makes life much easier. Wish I had discovered it sooner.
For now, all is well. Thanks for the help,
Bill
