There has never been a time when I downloaded a Synaptics touchpad driver and actually had it make a difference to whatever problem I might have...over the years, and the dozens of times that I have done this. I am very skeptical that going to their website will make any difference at all. In fact, I am convinced beyond any doubt. Due to the nature of the problem, I doubt that there is a solution (and my suspicion as to its cause). However, if there was one, the people in this forum would be the most likely ones to know of it. In the much more likely event that there is no solution, the people in this forum would be the most likely people to confirm that this is not an isolated problem, specific to my setup or system. I also haven't bought anything from Synaptics, it came as part of the PC. Therefore, Dell is the vendor. I hope it is OK to solicit information about this problem here.
That's not easy to determine. The only document I have that is 300 continuous pages is a PDF file. I tried a 150-page PDF file, and the erraticness of virtual scrolling is much less.
I don't agree that the facts implicate a problem with acroread 6.0. All indicators implicate the virtual scrolling mechanism, including the fact that it only shows up for very long documents, and the fact that virtual scrolling works by grabbing the scrollbar slider (as I mentioned in the first post).
That being said, I agree that one method to rule out the possibility is to reinstall acroread6.0. However, this has historically and consistently been associated with a host of time-consuming problems which I don't care to troubleshoot again. Logically, it should be still done if acroread is implicated strongly enough (which should be balanced off with the repercussions of the reinstall). Given how strongly that virtual scrolling is implicated, I would say that at this point, for my situation, the reinstall (and especially all its consequences) is not a justified.
Due to the difficulty in finding such large documents for this and other apps (300 pages or more), I posted only to see if anyone else has problems with virtual scrolling for large documents, as a confirmation of my suspicion. Due the suspected reasons for the problem, I wasn't really expecting a solution (though a pleasant surprise would certainly not be unwelcome). If you or anyone else has access to such a lengthy document, regardless of the application, it would really appreciate if this problem could be tested for. Or if you know of where such a document can be found, that would be helpful too.
I just created 1 300 page Word document (1 letter per line). It didn't have the rickety virtual scrolling. But then again, I didn't see the mouse pointer move over to grag the scroll bar when virtual scrolling. Looks like there are application-specific ways to deal with virtual scrolling, which may be the problem.
No, it does not. As in the case of Word, virtual scrolling does not seem to work by grabbing the slider on the scroll bar. This confirms my suspicions virtual scrolling works differently for acrobat reader than it does for MS apps.

Fred,
Thank you for using the Dell Community Forum.
This seems like a solution that the vendor of the software program that you are using should supply. I would seek a software patch if one exists.

Fred,
Does this happen in only one program or is it a global issue that is present in multiple programs?

Fred,
Since the issue seems to be with your PDF viewing program, I suggest reinstalling this to see if the issue disappears.

Fred,
Does this occur with long web pages as well?
