R6 IDW overriding dimension reverts to original value

I know that overriding the dimensions of geometry is not a good practice and
I avoid doing it. That said, however, it sometimes is the most cost
effective solution to a minor change. I have one part that needs to have
one dimension changed from .074 to .080. If I try to change the feature in
the model that drives this dimension, I get a cascade of feature problems.
I do not want to take time at this stage to resolve all of those problems
for the sake of changing this one dimension. I decide to make an exception
and change the dimension manually. I go to tolerances and change the
nominal value. Presto the drawing looks right. Almost done, but I forgot
some minor cleanup another sheet of the same drawing. I do that work and
then print the drawing. I happen to double check the first sheet and find
that the .080 I entered and witnessed on screen earlier has now reverted to
and printed as the original .074. Scary. Did I not change/override in the
correct manner? If IV won't hold an override, it shouldn't accept it in the
first place. What I saw happen was a dimension changing with no warning on
a sheet that was not being altered, when the model was not being modified
dimensionally. Sure it is all the more reason to avoid overriding a
dimension, but man this is frightening. You don't expect to have to recheck
things that have not been changed. I hope I did something wrong in the
override, but it seemed to work as expected until..... Anyone know what is
going on with this? Thanks.

I have something similarly but not so scary. I have a customer that wants a
" in the dimensions to show inches. I have this in my dimstyle as a suffix.
This requires me to edit the text in radiuses and diameters. I have to
remove the ". I have found version 6 putting it back in. At first I thought
is was a (edited) on my part but it has happened to many times. Had no
problem in 5.3

I guess I would be concerned WHY the other features are failing before I put
this part into my design.

I stated earlier that over-riding dimensions is not good practice. I avoid
it where reasonable. This specific incident is about the third time in
1-1/2 years that I have over-ridden the dimension. The point is, if
Inventor will allow dimensions to be over-ridden, they should not revert
without notification. It would be better/safer if it were not allowed at
all.
