dear mr erik (geek) riper,

i suspect that the problem you are seeing (file modified times) is the 
same as that for the person who posted an msvc++ "file changed.  reload?" 
problem (or was it a pre-compiled headers regeneration one?).

it might not be, given that there are two users involved.  i am aware, 
for example, that if you log in as user "root" the user/group permissions 
appear to be enforced, rather than over-ridden.  this is not normal for 
root user access, and threw me a bit first time i got a "SMB file is read 
only" message.
