Dear Maintainer,

To intonate a greek letter, you hit the intonation button, then the letter and the intonated letter appears on editor.

Sometimes texmaker appears the intonation symbol immediately when hitting the intonation button and i can't write an intonated letter.

Reproduction of the bug is easy. Write some greek words, then in a new line change language to english, write something like \section{} and hit enter for new line.

Change again to greek and the bug appears. Do this a couple of times if it doesn't appear immediately.

Also strangely, the problem fixes if you minimize texmaker window and restore it.
