Every time when I opened a microsoft office .ppt/.pptx or .doc/.docx file, i experienced a misbehavior that showed images behind text, making me think that it was a libreoffice/openoffice bug.
I have been wondering since like 4 years when you will correct this misbehavior,
and yesterday I realized that I just needed the correct truetype fonts.
I think that people (like me), should be warned when they try to open a file that need a particular font. Maybe a warning window with the “don’t show me this warning again” tipical checkbox.
People will know that it isn’t a bug and that is due to a missing font in his computer.
Guys, you have done a great job.
