I recently upgarded to elementary os juno. I had a few bugs that i sorted out but one that I can't figure out is trying to attach a file in email. When i click the "attach file" icon, the files window pops up and i can select a file but cannot attach it. The window doesn't have a button to allow me to add the file. It also doesn't have the close, minimize, and maximize icons. I have to press "esc" to close it. Anyone experiencing the same could maybe help me out here.Thanks.
