[ns] a strange problem of NS about blank

[=?gb2312?B?zfW9oQ==?=]

hi,all
I found a really strange problem when programing .
When I just added serval lines beginning with the symbol '#',
the result turned to be wrong!!!!
And I think there is no special reason except the bug of NS.
can anybody tell me the reason ??
thanks .
