I'm not sure if this has something to do with Mountain Lion or not, but since I've installed it, I can no longer copy and paste jpegs into TextEdit documents. Anyone have a clue? I certainly don't.
I've been doing this for ages, dragging images, copy and pasting selections into TextEdit, no problem until recently. I'll try this and see. Using another account is a good idea. I'll report back.
Updated: OK, this is strange. Did they make a fundamental change to OSX organization with the versions of OSX newer than Snow Leopard? Where I used to have a Library folder in my Home folder, I have none. There is a Library folder in a Shared Folder, but all it has within it is Application Support. Could these folders now be invisible? More checking needed. More help appreciated. Thanks!
Logging in as a different user does not correct the issue. I can select an image, Command C, Command V, or I can go up to the Edit Menu and manually select 'copy' then 'paste', and finally I can grab the image and drag it to the TextEdit document and while it acts like it will copy, nothing appears when I drop it on the document. I guess tomorrow I'll give Apple a call and let them earn their Apple Care warranty.
I'm starting to think this issue may be a result of using an older version of Graphic Converter, although I can use the methods I previously described to copy and paste an image into a Pages document while using Graphic Converter.
