Oh ghod I'm so sorry about that link! ] Mods! Please delete the link from my previous post if you can. CWShredder has just removed a 'cws affiliate winshow' cws virus from my IE system... so hopefully this post will make it through clean. Looks like I have to remove java from my system to stop this from happenning again. In case mods delete my post, here it is again: ***************************** It's a bit late to jump into this thread, but WTF... CorrectReference Professional is entering the later stages of beta-testing... ...and it has a feature to enable you to identify files within your textures/geometries which are not used by any library files. Could be just the ticket!! Howard:)) *****************************
