I am having the problem that ALT+ENTER does not insert a within-cell line

cell formatting.

Are you sure that alt-Enter is not working from the keyboard? Or are
you saying that cells in which you had done alt-Enter no longer seem
obey the forced line break?

If the latter, two possible actions might help. First, select the
cell and press F2. Second, select the cell, go to Format - Cells -
Alignment and put a check-mark in Wrap Text.

I often encounter the situation where Excel seems to ignore the alt-
Enter character
(LF) that is clearly visible in the cell as a box character. I don't
know why that happens. But asserting Wrap Text fixes the problem
forever.
