I am having problems with Word 2011 crashing on my iMac (OSX 10.7.5).

This may manifest as: 1) sections of text turning into question marks (as if you are trying to download text in a font you don't have) 2) your active window going blank; or 3) a blank dialog box popping up. Sometimes these spontaneously resolve, or partially resolve. Sometimes these occurrences are related to cutting and pasting or saving, but on one occasion I wasn't touching the keyboard at all.

Recently, I've notice that the text within the Word window will go blank when it is active, return when a different window (e.g. Safari) is open, then go blank again when I click back on the Word window.

Most frustratingly, the file will not save when it is in this state.

Despite reinstalling Office 2011 and installing all updates, including a firmware update, there are still random crashes that occur. As per some suggestions on the web, I've repaired a long list of disk permissions. Disk verification came out clean.

A coworker suggested that having Excel open at the same time was the problem, but closing Excel did not help.

This is definitely not a memory issue. I've restarted my computer multiple times, and closed all other windows, and have more than 90% of my hard drive still free.

Any help would be welcome!

Best,
Sarah
