Good gravy: another MS product self-destructs: this time Excel. Usually
'Outlook' has the honors?

(Did you ever ask yourself, "How stupid was the website designer that put
the sign-in button way over to the right, in 8 pt font, where you have to
cursor to move the screen so it can be accessed, rather placement right next
to " MS Office Online" title? Typically very thoughtless location by geekdom
personel? I suggest they go to white font on white background and make the
site completely unusable?)

I have a work book (xls.) full of macros designed to generate kanban cards
for Materials Management here at Steelcase manufacturing. I open, use, edit,
print, save and close 12 - 15 times a week.

About every third time using, I can add several lines of new part numbers
and pertinent related loc, qty, container, info etc, and then when I'm
finished, click 'disk symbol' to save, and it won't save. Click file, save
and won't save.
"Save as" und won't save. Click on info or solver, e help, and no
information is available. If I can get Evil program to close, I have to
re-add new info all over again nx time.

Specific questions to help/solver yield no discrete answers?

I am not running another programs. I get 4 diff error messages of why this
'save' action is untenable. 'File is not saved' is one of the more brilliant
ones, but to include, file may be 'read only' (it is not, no one else has
access), etc.

(With a hard copy published instruction manual length of 900+ pages, you
would asume that this help topic would have a ready answer, but no, you would
be wrong for the ten thousandth time about expectations of C/S from MS
products? MS has no concept of customer service, poor manopolistic dolts,
haven't a clue how to relate to a human user?)
Please keep characters limit to 16 (I live in a deeper cave than MS code wrtrs?)
