RE: I've always been in Multiple Window mode.
Do you mean Single Window mode? My recommendation was to switch to multi-window mode which I always use and it always works.
RE: However, I tried your suggestion as given and it fixed the problem. Now the column widths are staying exactly as I resize them.
Good!
RE: So why did this trick work, and how are users supposed to know this trick, and why doesn't QB support know about this trick?
Not a trick exactly, but a guess: QuickBooks was designed to work in multiple-window mode from day one back in the last century. Then some user interface designer thought it might be nice to only see one window at a time and that got added to QuickBooks. Probably a Mac user. When in multi-window mode, QB remembers the position and size of each window you use, and (it seems) the column widths as well, though by deduction based on my recent experimentation, it seems to save them in a different data structure.
So, I guessed that perhaps when in single window mode, QB doesn't see the need to save the window positions and sizes because they aren't used - and also because if it did and then if you switched back to multi-window mode after using it for some time, your settings would be trashed.
And then I guessed that in this case it was also not saving the column widths. Which if proven to be so, is a programming error.
I suspect Intuit support doesn't know about it because they know very little about QuickBooks in general. One rep in this thread even claimed QB doesn't save column widths. When of course it does and the rep should know that.
It likely hasn't been communicated to users or documented because it is supposed to work no matter the view you're in: There is no reason at all not to save the column widths when in single-window mode.
