It is also not saving in any window other than main chat now. Have to redo /chatf 8 in my secondary windows every time I log in now.
Agreed. I have to click on every window and tab except the main one to set /chatfontsize each time I log on.
The original post is feedback and not a bug, so I am closing this thread. You can shared feedback / request in other forums sections. Re: Imvi's comment about chat window sizes not saving, that issue should be fixed.
