The Print Preview function no longer works. Clicking Print Preview results in (1) a small window pops open in the middle of the screen then disappears (2) then a large window opens (to preview the content as it once did) (3) then the new windows disappears (shrinks out of sight) and apparently dies (4) "Print previewing message..." appears in the status bar until the cursor is moved off the page. In case it also isn't working, the system information includes: Windows 7 64-bit SP1 The Troubleshooting Information is: Name: Thunderbird Version: 31.3.0 User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Thunderbird/31.3.0 Profile Folder: Show Folder (Local drive) Application Build ID: 20141127140543 Enabled Plugins: about:plugins Build Configuration: about:buildconfig Memory Use: about:memory ... well, the rest wouldn't fit (something about a character limit) and the attachment part only works with images!
