thsi

i have currently a dual boot system of ubuntu8.04 and win xp. win xp has developed some probs like always and i have to reinstall it will thsi affect my ubuntu system in any way? i heard that GRUB could have some probs what can i do to prevent thsi from happening?

I face this problem, dont know why it happen only with rediffmail. I check mail & close the browser, then after 30 mins I may want to check again but have to relogin every time. Where as yahoo, gmail, hotmail all let u keep ur session alive for 12-24 hrs, so u dont need to login everytime...
