Hoster Power Hungry

[xxyzz]

Running vista 32 bit. All suggested changes have been made. I switched my settings to 16 bit 1024x768 that did not make any difference. My cpu usage is very low about 8% with only hoster open (idle) being used and no songs being cued.. Memory is at 41%.
My kma files are on the laptop but I have two 320gb hard drives installed. Hoster is installed on one drive and the KMA files are installed on the other drive. I would not think this would be a problem. Most of my song are imported from CD's but 25% are from zip files.
The bottom line here is when I am cueing up kma files it takes 10-15 seconds to load and this never happened prior to 4.0 coming out. It is not that big od a deal but does slow down my searching for songs. I can live with it, I am just curious if anyone else was having the same problem and I am probably trying to convince myself to buy a better laptop. I am one of those fools that are always buying the newest thing out there. However if buying a new laptop with 512mb graphics card vs what i have now (256) is not going to make a difference than I won't bother.
