I use Ubuntu Studio and this is 100% me being very nitpicky about having a pretty desktop.

I installed DropBox onto my laptop, and the indicator icon on my system tray was a strange grey box with a question mark. I didn't see any reason to keep it, so I tried to remove it.

First, I opened the settings for the indicator plugin itself, and hit a button that said "clear known indicators". It took everything away.

I didn't want to take EVERYTHING away so I deleted that one and tried to add a new indicator plugin so it would come back.

Except now, the entire tray is surrounded by a dark grey. Removing it and bringing it back does nothing.

Is there a way to fix my mistake?
