Whenever I do an operation in Word that results in a file dialog popping up, word crashes (the file dialog gets gray) and after a few seconds, the message 'Microsoft Office Word has stopped working' appears... After that the application closes (after having questionned whether I want to close or restart the application).
I also have the same problem in Outlook, but not in powerpoint and excel.

I'm working with Office 2007 running on a Vista machine. I've been working with it for more than 2 months without any problems, but this morning after startup the problem came up.

Thx for your help!!
