The overwrite bug previously noticed in 2.1.0 remains. If I need to overwrite something in the logging window (RST, Name, QTH etc.) there is NOT overwritten the highlighted character but the next to them - ie. RST - when the default 599 (with the middle 9 highlighted) need to change to 579, the simple overwritting of the highlighted 9 results in 597 entry. The same applies to ANY field in the logging screen. This bug shows in the Debian Stretch 9 with Gnome, tests in older Ubuntu/Unity versions were OK.
It is apparently a Lazarus issue.
I reported this bug few months ago but badly surprised that it remains in 2.2.0.
