CD 12.2 Does not allow auto complete in email

Since the last update sent out, CD 12.2 does not allow me to automatically complete email addresses in webmail. Normally you type the first few letters of the address you want, it shows up in a pop-down (which still happens), then you select the address and hit enter (or click it) and it populates the field. Though the address window still displays, neither clicking the address or selecting it and hitting enter will select the complete address.

This still works in Chrome and IE8

I’m using Windows Ultimate 7 64x as a user with admin rights.

I use neither themes or plugins.

CD is installed using default parameters

This is an issue on all four PC/Laptops I use.
