True, we may have screwed something up, but this is not 
what caused the problem in the first place.  In other 
words, there is a bug somewhere that should be fixed.  The 
fact that we may have screwed something up in trying to 
resolve it is not only irrelevant but it also does not mean 
the bug is gone.  Others in my company have had the same 
problem but were able to get around the bug.  Sure, close 
the bug report; we will start from scratch and, well, 
hopefully the mysterious bug will not come up again.........
Nevertheless, a big THANK YOU for your gracious 
intervention and attempts at solving this.
