(i use a SSD with 250GB's)

Windows 98 on Virtual Box:
- HDD: 10GB's;
- CPU: is 100%... Intel Core 2 Duo T9500 2.60GHz;
- Audio: AC7 is the best emulator sound that i have tested.. i had the Sound Blaster 16 before installed, but there was much more audio problems;
- i use 3 USB ports;
- Graphics: VBoxVGA... but i installed the SciTech Display Doctor with 128MB's.

i have notice several problems on Windows 98 on Virtual Box... but, for now, i need resolve the must important problems:
- i have notice the mouse on clag move and the Windows\programs need more time to open;
- the CPU seems to be 100% used;
- the sound can get trouble to ear, but plays.
can anyone advice me on how to fix these problem?
