Thanks @Speedie.

@MagicSmoker, For your efforts and other reasons posted before we take your posts very seriously.
Even when I'm not entirely thrilled about doing something I still try to do my best.
But just to clarify, note that Speedie's suggestion worked for pasting the seed and/or password into the text entry fields of the wallet, but "normal" copy and pasting (either ctrl-v or right click/paste) still do not work.
Also note that Speedie's trick is how you had to paste text into a command window back in Windows 7, so this is a 9 year old trick, more or less. Not something that sprang to my mind to try until Speedie mentioned it.
