Plugin changes not stored

[MSpagni]

In my usual XP machine I tried to change the pdf plugin to use an older version of PDFtoText as I already did with the previous versions.
The change is operative but is not stored, so each time I close and reopen EDP the chages are lost.
I tried creating a new plugin for it instead of modifying the standard: no way. Same result.

Indeed, a bug in 15.0 Beta. Will be fixed in the next build, today or tomorrow.
