The background is this. Suddenly document viewer wasn't in the list of options to open a pdf a while back. I've always used Evince so I found and installed it. All was well, but now it only shows the Adobe logo, not the front page of the pdf. How do I fix that, and is it connected to the fact that Mint doesn't seem to have an up to date version of it? (It used to just be a case of renaming the file but this doesn't work any more.)
