New user of Libre here and so far it is doing the business.
I was using Open Office, but unfortunately OO keeps crashing File Explorer on Windows 8 and it seems it has not been fixed so I installed LO instead.
Just thought I would say adjusting the memory works great, mine now goes like a rocket having set it to 400 meg.
I would venture to say for modern machines the default memory settings are too low, but it is what it is, a pop up the first time the prog is opened would be useful for newcomers, because of the lagging I thought my computer was downloading updates, lol.
The menu shown above can be found at…
