[pushpraj4u]

Hello All,
I have installed VirtualBox-3.0.4 on fedora 11. and using winxp as a guest os.
Everything is working fine but when i use fox pro in my guest os i.e. winxp. fox pro hangs and works very slowly.
Any idea what i need to do???
I am first time using Virtual Box. but tried this on other machines but same problem.
Please help me.

Thanks,
Pushpraj.
