erno 0 Report post Posted November 16, 2006 If moving block, with vertical blocks=off, insert mode=off (block cursor), then undo is replacing characters at the block position, and not insert the text there. Example: first text: 123456789 selected 12, cursor position on 5 after move: 3456129 after undo: 1256789 should be 123456789. If vertical blocks=ON problem does not happen, because moved block is replaced with spaces. Share this post Link to post Share on other sites
