No, I always select the region, then begin <query-replace>.

When I see the previous replacement in the command window:
   Query replace in region (default _nmRoot → _nmDolRoot):
Instead of:
   Query replace:

Then I get the bad behavior.

Do you mean that the region is deactivated after finishing query-replace?
That's how it's supposed to work.  Please always select entire region
before starting query-replace again.
