James, how big is your C:\ drive and how much free space does it have? I know you have enough memory but hard drive work space can also effect those things. Search and importing are the most memory intensive things you can do in Hoster especially when playing at the same time. If the drive is heavily fragmented or has limited free space to work in, then things like those will slow things down.
It is kind of like trying to listen to streaming audio over a modem connection.
