yes I use same browser, yes forms are same too, but operating systems and versions of clearsilver and python differ.
I give NCR values when I run my code on a windows xp system (also a freeBSD server), that use clearsilver
ubuntu (7.04) with clearsilver 0.9.14 and python 2.4,

but I give my data in other format when I run my code on a ubuntu linux (version 7.04) with clearsilver version 0.10.3-4.1 and python 2.5.

(my client for viewing pages is same)

any help would be appreciated
