There is one spell checker bug: When I end a paragraph with a full stop and then press enter then the red underlined mis-spelled words are "unmarked" as in the red zig-zag line underneath the mis-spelled words disappears and I cant correct them any more or lose track which words are mis-spelled. The red zig-zag lines underneath the mis-spelled words should never disappear until the word is spelled properly. Thats a BUG.

To make the red underlines re-appear I have to rightclick....untick "Check Spelling" and then activate it again. Thats too complicated.
