Acro 9 Pro Extended on Win XP.
Searched the settings, the help files, and here on the forum without finding an answer.
In Acro8, there was a checkbox to open new docs in a separate window - unchecking this box defaulted to opening multiple docs in tabs.
Did this disappear in Acro9? I prefer to open multiple docs as tabs, giving me one application window in the Status Bar.
One workaround taken from this [url=http://kb.adobe.com/selfservice/viewContent.do?externalId=kb405108&sliceId=1]technical note[/url] is as follows:Group similar taskbar buttons together in Windows XP and Windows Vista.
1. Right-click on Start and chose Properties.
2. Select the Taskbar tab.
3. Check "Group similar taskbar buttons".
4. Click OK once.
This will effectively collect all Acrobat windows into a single taskbar button which will also let you select the window you want to work with and reduce clutter.
