# Are there any known issues?

There are some known issues as listed below. These should be taken care of in the future releases, but solutions to them are not yet in sight.

- When the Line Endings drop-down menu on the toolbar is opened, no check mark appears next to the selected item.
- When Line Spacing is set bigger than 0, the underlines, that Japanese input methods show during Kana-Kanji conversion, are displayed lower than usual.
- When “Fix line height with composite font” is turned on, white lines may appear between the lines inside the selection (i.e. the background-color can be seen through).
- If you selected Cancel in the authentication window of “authopen” when saving, error logs are output to console. (“authopen” is the name of a helper application which is launched by CotEditor.)
- When print previewing on 10.3.9, an error saying that “Can't create CMap Adobe-Identity-UCS2.” is output to console.
- When completing words on 10.3.9, after typing only one letter and showing the completion list (usually by pressing F5), pressing Enter doesn't select an item.
- When completing words on 10.3.9, pressing ESC doesn't pop up the completion list.
