Having used LibreOffice on Linux for quite some time, I recently tried to install it on my Windows 7 system. Finding the libreoffice.org site, I was directed to download the “Fresh” version (although at that time I was unaware of any other version). Upon installation, I was amazed to find that version (5.1.0) unusable. The side panel did not appear, only a blank screen. The menu was invisible, but usable: hovering over where the “File” menu was supposed to be exposed the expected options. Clicking on “New” and “Spreadsheet” resulted only in a blank colored screen. I can’t believe that this happens with every user, but the only things different about my installation were an AMD processor and the fact that I chose to install it to D:Program Files.
By Googling, I found out about the “Still” version (5.0.5). That version installed and has worked perfectly so far. Thus, the problem appears only with the “Fresh” (5.1.0) version.
