A slight step backward in MS Word compatibility...
I've been using LibreOffice since I got my latest laptop; I've been telling myself I'll fork out for Office365 if I run into anything that LO can't handle. It's been nearly a year, and so far no need. But today I upgraded to 5.0, and this afternoon I tried to open a change-request form from our hosting company. I've been using this form just fine for months now; it has a nightmarish little mess of Word tables and a stupid number of font changes, but LibreOffice-prior-to-5 handled it OK.
Sadly, 5.0 mangled it: made wonky font substitutions, and totally destroyed the last table (the bit where I specify the date, window, and time zone, so non-optional.)
So I had to choose: fix the form, or buy Office365? For the moment, I fixed the form...
ETA: I should mention that otherwise I'm liking it: all the Excel files I've opened have been just fine, and the load time is significantly improved.
