Repository with LibreOffice 4.4 for Fedora 21+?

Side note... You probably need to modify one of your yum configuration files to tell yum to ignore LO updates.

OK, I followed everyone's tips and was able to replace the Fedora
repository-installed LibreOffice 4.3 with 4.4 installed from the RPMs
downloaded from the LibreOffice site!!

Sorry I've never tinkered with YUM configuration before, how to I
modify it to ignore LibreOffice updates?

Another strange thing is that when (and only when) I enable "Use
OpenGL for all rendering" in options, (1) all vertical scroll bars
become upside down (i.e. the bar moves up from the bottom when I
scroll down), (2) all checks in checkboxes are upside down, and (3)
when I resize a window the expanded area is all dark! Has this
happened to anyone else??

Thanks for your replies!
