This does not look like a popup, is it really one or does it stay there for
as long as some windows are open? It looks like the standard button-based
application list, I don't remember the name of it right now.
You should be able to remove it or move it to somewhere else just by
rightlicking on it (or to the space left of it). This may be tricky since
your bar is so full.
If rightclicking it doesn't work, create a new taskbar (it will come out
"naked", with nothing on it) and add plugins, applications starters, etc. as
you wish. Then the problem should be solved.
