Has anyone else noticed?
Adobe Acrobat XI for Mac freezes and force closes constantly, taking all your open windows and work with it.
And it constantly refuses to save modified pdf files in the same location as the original, even if you renname them.
Adobe, having had these bugs brought to its attention, is either too incompetent or too indifferent to fix them.
The inescapable conclusion: Acrobat XI for Mac is built to fail.
