Challenge accepted... I backed up the wallet.dat file that I had created by doing restore from seed my way (ie - using command line switches) and tried restoring from seed by selecting option 3.

All seemed to be going well until I found out I had to manually type in the 25 word recovery seed because copy and paste was blocked - and yes, this is Windows 10, not Windows 7, so I should have been allowed to paste in the seed. Needless to say, having to manually type in the seed is frustrating, time consuming and prone to typos, and I can't think of a single benefit to blocking copy-and-paste so that should be addressed before releasing the wallet to the wider world.

And yet again y'all roped me into bug hunting...
