Thanks for the info, onelove! The customer who tested this while we were on the phone indicated that the button disappearance was intermittent. Sometimes the submit button appeared and stayed put, other times it disappeared. This in itself suggests there is no problem with the CSS.
Interesting that you're experiencing the problem in 1.3.8a -- seems to negate the idea that it was a bug fixed in the current release.
Also interesting that you're experiencing the missing button when using IE7. I tried more than once to create the missing button behavior with IE7, but none of my systems have hidden the button -- at least not yet.
Wondering if the common thread might be a security app such as Norton. Or maybe an obscure security setting in IE preferences? And if this is the case, what exactly would trigger the behavior? I'd expect the IE users who report this problem with our create account form to experience similar hang-ups when submitting similar forms on other web sites.
Maybe a virus?
