I don't remember that it could be resized in that version. Is there another problem besides the lack of resizing?
Thanks for responding. This version has previously allowed for control over the window size, and for movement of the window between screens and around on a screen - those functions have been lost. The screen size arrows in the corners, and the "roof" in the lower right corner are there, but inoperable. The command for the windows to mimic the original size - set at 25% - has also been lost so it seems like the command - set at "Properties/Initial View" - for magnification at 25% and "resize window to initial page" are no longer being honored. Also, the "Settings" box at the right side of the Save As Window is greyed-out or inactive.
I never noticed the resize "roof" in my Acrobat Pro 9 SAVE AS dialog, but there it is. I can increase the size but not decrease it below the original size. Since I have no ideas on that, let's look at the other issues, which might illuminate the first one. I don't understand what you mean by "The command for the windows to mimic the original size". What is that?
The Settings button in Save As is always greyed out when saving as PDF. It is available if you choose some different types. That, at least, is normal.
The system is set for initial pages to open as single-page continuous at 25%, but now everything opens at 31.5%. Even if I select the document properties to resize window to initial size, it no longer does so. Finally, my Save As Window is "locked" at full-screen covering the initial Acrobat document screen, cannot be moved to the adjoining screen, and cannot be downsized, as you say that you can to, but not smaller than the original screen.
By the way, daily security runs have revealed no issues there.
This all just happened. Unless you have another idea to try, I'm going to re-load the application, as it would seem a glitch there is now the most likely issue.
