Natural runtime - word problem


on our clients we are using Windows Vista (SP1), Microsoft Office 2007 (SP2) and Natural Runtime 6.3.6 Patchlevel 0000.

When a user opens a Word document from inside of Dialog (Natural runtime), and returns back, somtimes there appears an error message “4601 runtime error”. Seems to some kind of makro error.

Any suggestions what we can do to fix this problem?
