File paths containing spaces are not remembered by Save As in Reader
I save certain PDF files to my Windows (10) Start Menu, usually in folders which, like "Start Menu", contain at least one space in their name.
The list of folders to which previous files have been saved apparently refuses to remember such folders, forcing me to copy-and-paste the applicable name /every/ time I want to save something there.
A folder name that does not contain any spaces, is remembered as usual.
