Shrinking Clearance Holes

[WDG57]

I'm having a problem with clearance holes shrinking in my models. I'll put in a "free fit", counterbored clearance hole for an M4 screw, for example, and it looks fine. Later I notice that the hole has shrunk to about 2.7 mm. (The counterbore doesn't change.) I'll redefine it and save the model. Later, I'll notice that it has done it again! This is quite annoying if I have many clearance holes. Anyone else having this problem or know of a solution? Thanks. WDG

It is possible that some dim from the hole is linked to a param or another dim that causes a change?

Do a Parent/Child of that hole to see it's links.

Don't think that's the problem. Most are just standard clearance holes located from two surfaces. Others are the same except they have been patterned. The entire pattern changes.
