I see that despite unchecking the option of making this program my default pdf program, it tried to do so anyway
Yes I had the same problem – in my case it succeeded and I had to reset to my default pdf program.
Mind you this does seem to be a good pdf editor. I nearly didn’t download it as there are so many so-called pdf ‘editors’ that turn out not to be able to edit the existing text – they just ‘paste’ over the top.
This one really does properly edit the existing text, so I’m very pleased to have it. It does have the same problem though as a lot of pdf editors, in that if you try to edit text where the full character set hasn’t been saved in the pdf and you type a character that doesn’t exist in the document in that font, then it does a substitution – i.e. it doesn’t use the same font. It does a reasonable job at choosing a substitution font though.
It seems fairly easy to use and intuitive.
It also has digital signing, which is nice
Shame it is just a one-year licence.
