I use Adobe Acrobat 8 Professional. Somehow, I closed the thumbnail views that would appear in a column along the left margin of the pdf file. Does anyone know how to show the thumbnails? They are a great help when manipulating a document.
Also! Does anyone know how to hide the right margin? It’s just a waste of space when there are more important things to show!
In Acrobat XI, you can turn the side navigation options on and off and select different options via View | Show/Hide | Navigation Panes | [Page Thumbnails].
Adobe has rearranged the menus and features a number of times in recent years and I can’t say version 8 has the same menus, but somewhere should be a similar command. It’s not just thumbnails, but all “navigation panes,” so look for that.
I’m not sure what you mean by “right margin.” Most of the panes in the Acrobat window can be minimized or hidden, though. Same general process of looking through the menus. For just reading a document, select Full Screen mode (Ctrl-L) or Read Mode (full window, Ctrl-H).
Amateur Barbarian, I will try your suggestions and post back. Also, I will take a closer look at what it is that bugs me about the right margin. Off-hand, I even had to ask myself "if I could do away with the right margin, what would that gain me? It’d just be a blank area…adding nothing of value to my view! I must have had some thought when working in Adobe about why it was bugging me! I’ll let ya know! 
Ok, one mystery solved! While I found how to show “navigational panes”, the thumb nails were still missing! I am not sure why or how I lost them, but I did find them! In my version of Adobe Professional, I found: View > Navigational Panels > Reset Panels which brought back my thumbnails! THANKS A BUNCH, A.B.!
Also, in Adobe Professional, I see there is no annoying panel on the right. Sometimes, my PC opens in Adobe Reader instead (not sure which version off-hand). I will have to look into this further and observe when this useless panel appears on the right…and what could be done differently.
