Maybe that adds to the slowness I had already, but my spreadsheet was
slow with 3.3.4 too. I upgraded to 3.5.5 earlier this week, and I'm
not sure it is slower now, but it is certainly not faster.
But I'll install 3.6 when I have some time left and see if there is
any difference.
There are so many other things that are very slow as well, for example
auto-filter and diagrams. I have one diagram in another spreadsheet.
It use data from 365 rows (one for each day of a year) and something
like 5-10 columns. If I want to change the size, for example, of that
diagram, I need to wait for several seconds, maybe 30 or so, before
anything happens after I double clicked the diagram.
I also made a similar one for a month, that is 31 rows and about 5-10
columns. It's faster than the year one of course, but still too slow
for most situations. If it was millions of cells I would understand
it, but 365? That's nothing! Right?
Kind regards
