First of all, this is a fabulous addition to KM and IR, so big thanks for providing it.
Bottom line regarding my sad story is that all issues, except part of the last one, are now resolved, as most were due to my errors.
One comment and follow up question about #4 - conversions:
No problem with conversions, it's a small thing: Due to the structure of what’s on the clipboard coming from IR, ExtCalc aborts and does not translate anything. Remove couple rows and EC works great

.
I have a question regarding this:
mr_d_p_gumby wrote: The Hex Cmd << Buttons button does the reverse. They're mainly useful if you are typing the data in manually, rather than pasting it from IR
I must be misinterpreting something because readme suggests this use:
3. 'KeyMove Calc' sheet
This is the expert bulk mode KeyMove code calculator. You can convert
a KeyMove list copied from IR to button strokes, make changes with
Excel's find & replace command or a text editor of your choice, and
then convert them back to KeyMove codes that you can import back into IR.
I can see that what you’re suggesting can actually be done in IR anyway. But the big-list handling while setting up a remote for the first time, is fabulous. The list does get translated so you can actually know, quickly, what you coded previously. I haven’t looked into the effect of/on the notes field in IR yet, that comes next.
Several responses to your kind answers are in order:
Re #1 – yes. I had two RDFs, oops. The one in RDF directory plus a leftover from, I think, extinstall run in IR directory.
Re #2 – was my error and EC couldn’t decode some wrong hex numbers. Simple.
Re #3 – Yes, I was refering to ‘protected’ and did get in without a password, so this no longer is a problem. Also, I must have been using it with my eyes closed

and tried to paste hex codes without using the button and excel didn’t think kindly of that idea. Thing is my mouse has been trained by Mark

He drilled into the poor thing to do paste special/values always. Now when excel is anywhere near jp1 that’s the only thing the mouse does

. Sorry for the alarm.
