Middle click and drag in Adobe Reader scrolls the page, as it does in most Windows applications. However, middle click and release (without dragging) shows a page thumbnail.


Is there any way to turn off the thumbnail-showing behavior? It's annoying when I just try to scroll the page and suddenly a box pops up, obstructing the text.

Can you add a screenshot? I ask because I can not duplicate the same issue with my Adobe Reader. – SgtOJ May 27 '12 at 22:54
Which version u use? – blasteralfred Ψ May 28 '12 at 7:51
This is what the thumbnail looks like: I'm using Reader 10.1.13, but it has been happening in previous versions as well. – hmp May 28 '12 at 11:10
Do you still want to scroll with middle-click? If not, then your mouse drivers should have capability to outright disable middle-click for acrobat reader. – Mxx May 31 '12 at 19:44
Well, if I didn't want to scroll with middle click, I just wouldn't use it... – hmp Jun 1 '12 at 20:41

AFAIK there is not a direct way to do this so you have to use some trick like AutoHotkey. There is another question I found where user is using mouse wheel as hand in Adobe reader.

The best way to set the keys according to your wish and do whatever you want to. But I think this will cause to not scroll down through the mouse wheel after this.

Not in the direction you wish to hear, but in my opinion Adobe Reader is one of the worst PDF readers around, suffering from serious bloat. Therefore, many people avoid these bloat-caused troubles by using alternative readers.

Some free PDF readers that I recommend are :

Foxit Reader
PDF-XChange Viewer

These readers are much faster while doing the same job as Adobe Reader, and their Support actually responds to queries and suggestions.

(To the moderator who deleted my previous answer : I do think this is a good advice when the way Adobe works is unacceptable.)
