Yes, this is not unusual. The bug has an "unstable" behaviour. In some
positions, it doesn't occur... but many positions have been found where it
occurs (sometimes, the problem is i.e. that Fritz 7 doesn't consider that the
opponet can play O-O-O). Furthermore when going through the notation in analysis
mode, it can happen that it sees the move, and then again doesn't see it, in the
same position.

I am told CB has fixed the bug already, and the new engine version will be in
the next update which (hopefully) will be released shortly, whereafter SSDF btw.
will start to test Fritz 7, too:
