[galenthurber]

GUI  shows typical bottom layout.

Reactions are enabled.

I attempt to select a reaction NOT in my recent reactions, nothing is select able.

text line for reactions is nearly black text on black background, my windows theme is not similar.

Can not screen capture pop ups.

Also in chat window the reaction pop up is off the screen to the right, unable to use there
