Question : File saving problem in Office 2007

I recently upgraded to Office 2007. A strange phenomena happens: I make a file (in Word or Excel) and save it. When I work on it and save it some more times, suddenly I get a message saying it can't be saved. The message is (translated from Dutch): Word cannot finish saving the file because of an error with the authorisation of the file.
The only remedy is to rename the file and save it. And then the whole process starts again.
How can I get rid ofthis?

Experiencing similar issues.  Did some searching and found a link that may help.  Due to the vast number of possible issues, it'd be too difficult to give you a straight answer.  However, it does appear that turning off Offline Files appears to fix this.
