Unable to scroll down on my sheet on IE8 and windows XP

Unable to scroll down on my sheet on IE8 and windows XP

Hi there
 
since the upgrade to zoho i can still access my zoho sheets ok, however, i am unable to scroll to either side or up and down to access more of the sheets.
 
I seem to be able to do this from my home computer so I assume it is a compatibility issue with IE8 and windows XP? as i am not an administrator on my work computer I am unable to upgrade to IE9 or switch over to firefox etc. Will this issue be getting resolved at some point?
 
Cheers
