eBay

I cannot update item specifics from the seller hub, every time I click on the box to add specifics it does not allow until n unless I open the revise item to do the needful.

I cannot add item specfics until and unless I go to revise item, secondly eBay does not allow me to send a message to buyers question until I copy and paste, cannot type in the message box directly. This problem prevails for 3 months now. Please help...
