[GNC] Save button never seems to activate anymore

[G R Hewitt]

Greetings all,
MacPro 2010, High Sierra Gnucash 5.0

I have noted that the 'Save' button never seems to come on anymore.
Recently, after doing a few things to the accounts, it showed active and
I'd click it, when the little watch appeared and then the 'Save' button
would be
deactivated, until I made some other change, when it would reactivate.

This is no longer happening, and I have tried changing things and entering
new things
and the like, but still there is no change in its deactivated status.

When I close and re-open, all the changes made are there, so there's no
real problem about it, other than I found it reassuring to manually save.

Any idea's on this? Thanks in advance.
