Blaze Thursday

Sometimes when I log in and/or change forms the white of the eyes I'm wearing seem to bulge through the upper cheeks. This only happens sometimes though and seems random. I try changing skin, eyes, dropping the Ruth folder then rewearing everything again, relogging, clearing cashe etc but seems to just eventually go away...very anoying though for taking photos and such! Any ideas on quick fixes?

What is the commant or button sequence to crouch?
