I’ve changed the «special window arrangement» and now the impress doesn’t work

I’ve changed the «special window arrangement» and i have great problems:

-normally the Impress disappears when I push the mouse on it.

-It doesn’t appear the minimize, and maximize possibility

I have deleted the file 4 in .config, i’ve tried to use the secure mode, and it doesn’t work anything.

Any idea?, please.

Thank you
