I copied the seed string by selecting the text with my cursor then hitting ctrl-c to copy. Then I opened an administrator command prompt and pasted the string into it using both ctrl-v and right clicking the mouse and selecting paste - both worked.

So pasting into a command prompt works fine, as it always has in Windows 10.

Trying to recover from seed again, when I hit ctrl-v to paste it shows a non-printable single character; looking closer, it appears to be a ? in a box, so I guess that translates as "unprintable character".

I cannot right-click while sitting at the "Enter seed (25 words):" prompt. Trying again, I also cannot paste using either method to the password prompt.

Right clicking on the title bar for the command window that the wallet is running in and selecting "Properties" I also checked the checkboxes under "Options" and all were enabled EXCEPT for "Quick edit mode," but enabling Quick edit mode didn't change anything. Still can't paste.

And yes, copy-and-paste works fine elsewhere.
