Wow, so this one stumped me. If you have two Word 2007 Windows open at the same time, when you switch from one to the other, either by alt+tab or by viewing them side by side and clicking one then the other and you get the hourglass, then this might solve your problem.
My clients were having the slowdown after upgrading to Word 2007. But we have Adobe CS2, and some clients that just have Adobe Acrobat 7 installed. The problem is that there is an Adobe Pluggin in Word causing the slowdown, and not that Virusscan is scanning files for viruses on file opens or some other nonsense.
To disable The Acrobat PDFMaker addin, follow these steps:
- Log in as Administrator.
- Open Microsoft Office 2007.
- Click the Office Button in the upper left.
- Click Word Options in the lower right.
- Click Add-Ins on the left.
- At the bottom, make sure ‘Com Add-ins’ is selected in the Manage: drop down and click Go…
- Un-check ‘Acrobat PDFMaker Office COM Addin’ (Or whatever you think might be making Word 2007 slow).
- Click Ok.
- Close Word.
- Open Two Word Windows. Now you can switch back and forth instantly!
This will work for all users on the system!
