Thanks for link and ideas.. on what doesn't work.. the Clipboard Capture bottom window just shows as plain text. Ironically more complex rtf format does paste into Scrivener.
Details of my experimentation:
The Scrivener clipboard capture is interesting.
If I copy something as plain text it shows as such in bottom window as plain text but usually.. will not paste into Scrivener. But when I first started experimenting it did a few times, than stopped
But it seems to convert it in the upper window to rtf text and when copy the rtf text it WILL paste into Scrivener
Thinking my first few times pasting plain text worked though maybe it worked awhile after a reboot.
But rebooted again and txt text won’t paste. But it did briefly earlier when started this experiment.
This may explain why I can paste from with Quickpaste in ClipCache that captures all clips because it seems to do the same as the Scrivener clipboard - converts it to rtf which will paste into Scrivener but not just text..after a few copies/clips.
From the good link and others this appears to be a fairly widespread Windows 8 issue but with different solutions and combinations of programs. I tired some of the suggestions, like num-lock on and off, I don’t have bluetooth, and I also have 4 monitors so tried to see if copy paste in same monitor vs different and some of the other ideas. None of which worked consistently.
Sometimes I can paste into Scrivener with just paste and will work but not as paste and match style .. but just did again and confirmed plain text won't paste as either now that I have been experimenting with it.
But I can't find other consistent patterns other than seems to always..so far.. paste rtf fine just usually not plain text...
From websites, html will paste but not paste and match style.
This is all on win 8.1 running from desktop not Metro. Using Start8 so never have to look at Metro and desktops look just like Win 7 plus some features.
I also tried on laptop also running 8.1 with same result, plain text won't paste but rft and html will. I am using SugarSync which works great to sync Scrivener so can use in both places of house. Often I copy stuff from various sources paste into text editor (Textpad) to rewrite or just use parts etc. Then use Scrivener to organize by topics I use for newsletters and other things. Use to use OneNote but much prefer Scrivener now... and it pasted txt fine when using Win 7. At least the workaround is fairly easy.
