Hi;

I’ve been getting reports from users that they can’t type in certain custom fields in the publish page for my blog.

They use Windows—mainly I’ve gotten(and confirmed) this issue with people using Firefox, but I have run into at least one instance where the person was using Internet Explorer.

Most of they time, it is fixed when I switch from text to textarea—but why this should be, I don’t know.

This has happened on two different installations of EE that I have access to.

You posted this to the pMachine forums, not the EE ones.  I’d first start by checking out this entry in the Knowledge-Blog.
