To come quickly to the point, here is the problem / issue (hopefully, in the most concise and useful formulation).
OS: openSUSE Linux 12.1 with kernel v. 3.1.10-1.9 and (just for the report - even if I don't think it matters) Qt libraries v. 4.7.4-19.6.1. I say I don't think it matters, because I've already experienced this very same issue with openSUSE 11.0 (kernel 220.127.116.11 and Qt 4.4.0, with Acrobat Reader 8.1.3).
Acrobat Reader v. 9.5.1 (the release included with the distro).
The issue: when I try to overwrite an existing PDF document (i.e.: save 'foo.pdf' OVER a pre-existing copy of 'foo.pdf') I systematically get caught into the sequence 'the document already exists. Do you want to overwrite it?' -> yes -> 'An internal error has occurred' -> the document can't be overwritten.
Attempts to fix: I've already tried - suspecting I had possibly missed something during the installation process - to change the permissions of the '.adobe' preferences folder under my /home directory by issuing the usual 'chown -R xxx:yyy .adobe' command: with no result.
Any idea about the possible causes and workarounds?
BTW, while I was trying to recover the exact information about the program's version in the 'Help -> about Adobe Reader' menu, I've stumbled into another issue (which looks very much like a bug): that is, the program freezes if I try to read the 'Credits' information by pushing the suitable button in the red 'Adobe Reader 9' banner. Possible causes and remedies (aside from upgrading to the most recent version)?
Thank you very much in advance

I add this one to my previous message, which solves the issue (and closes the thread).
The issue has been solved (on another system, though: that is, Fedora 17) by installing the original Acrobat Reader 9.5.1 from Adobe. With "original" I mean: not the .rpm archive enclosed in the OS DVD, but the one which can be downloaded directly from Adobe.
The method: one has to open a terminal and simply do the following:
[as root] # yum install AdobeReader_enu
The version of Acrobat Reader which is installed by this method is complete with all the GTK suitable libraries: and actually works with no hassle, allowing to overwrite previous versions of the same file.
Now, however, I have to find some equivalent procedure under openSUSE: because it's a fact that even the AdbeRdr9.5.1-1_i486linux_enu.rpm file one usually downloads from here installs a copy of Acrobat Reader which shows the aforementioned issue, despite all the necessary graphical libraries being already installed in the system. Now, since this one is probably the .rpm archive a user finds in the main .rpm-based Linux distros, I add that it might be interesting if some Adobe engineer would try to dig a little deeper into this issue...
