(This was originally posted a week or so ago in what turned out to be the wrong forum. I can't move the thread, so I'm reposting it here.)
I've been googling and searching for this for some time; the only other post I've found[*] with the same problem never got an answer. So here goes.
We're using Acrobat reader 9.3.0 on XP. I'm not very familiar with the software used to create the PDFs; trying to ask the authors what they used got a semi-garbled reply including the words "presentation adobe photoshop cs2", if that helps any. (Their English is only so-so, and there's at least one layer of overworked translators between us, so there's a good deal of mind reading going on.)
Pulling up any of the PDFs in Full Screen Mode starts a sort of slideshow, advancing every few seconds. This is hellishly annoying when trying to read more than a few words or follow more than an inch or two of a line diagram. I tried bringing up Preferences, selecting the Full Screen tab, and unchecking "Advance every ___ seconds", but this had no effect. Exiting the reader and starting it back up after making the change also had no effect (and I double-checked that the box is still unchecked). I was going to try checking the option and then typing a 0 in the space, but it gave an error that the number had to be 1-60.
Setting it to 60 delays the slide show for a minute, for whichever page I happen to be viewing at the time of bringing up the Preferences window, but after autoadvancing to the next page, it reverts to advancing every few seconds.
The "left-click forwards, right-click back" option was checked, and that does work, but having to continually hop back a page and find my place in a diagram again is tediously unproductive. Hitting the space bar just advances the page immediately, trying other space bar combinations had no effect.
What option(s) do I need to twiddle to turn off the autoadvance altogether?
