I assume this is where you post bug reports for Version 1.0, If not please tell me where to do so.
If you use Ctrl+A in the editor (only tested in the “Other Editor”) to select all text and then try to copy the selected text using the mouse’s right button popup menu, the entry “Copy” is grayed out.
If you select and highlight ALL the text by dragging the mouse with the left button depressed–everything works correctly.
I had previously pasted the entire page into the editor, made some changes and wanted to copy and paste the corrected content elsewhere. So this might not happen if there had not been a previous paste operation.
