R18 Strange behaviour

[CATPart]

Few days ago, we switched from R17 to R18... when I opened one project in R18 to see if everything works fine I noticed some strange things:

1. Assembly needs update of some parts and nothing has changed (when opened in R17 no need to update).
2. Axis system color changed to black without any modification of graphic properties

Has R18 some known bugs? that might cause this kind of behaviour.

1. Make sure your settings are the same in both releases.

2. Sometimes CATIA changes the math between versions and that will force updates at the new version (hence CATDUA). I don't know of anything specific between R17 and R18, however.
