Acrobat - Tool Bar (left side): how to hide permanently?

Hello,

is there anyone out there who knows how to permanently hide the Acrobat Reader left side Tool Bar?

Before the last update, the docs were instantly shown on my screen in an readable size without any of those tool bars because i could hide them permanently. Now it opens every document with that dang Tool Bar on the left and with a small sized doc which no one can read as long as you click away the Tool Bar every ** time. It's THE worst and most annoying thing Adobe did since sliced bread...!!!

So, jokes aside - how in the world can i change that??

Thanks!
