Question for you. Did you recently apply one of the upgrade patches to Poser right before this began occurring or you started to use the plugins? The reason I ask is that if you don't delete the old plugins before updating and adding the new versions of the pulgins you can have problems just like this. If that is not the cause, then you will most probably need to re-install and patch the system files in the Poser root directory. You probably do not have to mess with any of the subdirectories, with the exception that you might want to wipe the plugins and update them to the current patch version. If you do have to do a full unistall/re-install your user modified files should be okay. Like many others, I find it prudent to keep a backup copy of my critical Poser program files on hand so I can just delete and copy them back if something becomes corrupted. Saves on having to go through the whole uninstall/install/patch routine. But as an added thought, don't forget to heed Mason's advice. It may be that Poser alone is not the problem.
