I'm not certain of your dilemma, but I'll give it a shot.

I presume that one or more of your tool bars is out 'floating' over the grid
somewhere?  If so, simply move your mousepointer next to the title of that
toolbar and press and hold the left mouse button.  You should get a cross
with 4 arrowheads, just drag up toward the normal docking area and when it
gets close enough, it'll 'jump' right into place.

Now, if you're not happy with the place it jumped to, then look for 4 dots
arranged vertically at the left edge of the menu/toolbar, and you can move
your mouse pointer over them and again press and hold the left mouse button
to grab the bar and move it around some more.

Hope this helps some.
