I'm trying to sync my Omni Focus iPhone app.

Among the options listed (MobileMe, Bonjour, WebDAV), I have selected the MobileMe option.

When I attempt to sync Focus on my iPhone, the system automatically prompts me to enter my my MobileMe login credentials, but I cannot enter my login name and password because the system has grayed them out.

I'm really frustrated that it's prompting me to enter my login credentials, but it doesn't allow me to input them. Does anyone have any idea why this is happening?

In general, I'm a big fan of Focus and Omni Products, but I've spent several hours trying to fix this problem and about ready to move to Things or some other app. Thanks,
