Some customers have reported system lockups that are related to the InDesign feature called Type Contextual Controls.  You will know this feature is enabled if you see a little 'o' icon that appears briefly next to the cursor while you are editing text in a document.

If you are not using this feature, we recommend that you turn it off. Here is how to turn off this feature:

1. Open the InDesign Preferences dialog.
2. Select the Advanced Type section.
3. Deselect (uncheck) both of the following check boxes: 
           • Show for Character Alternates, Fractions, Ordinals, and Ligatures 
           • Show Adornment on Text Selection/Text Frame for more Type controls
4. Click OK to close the Preferences dialog.
