In IE6 I cleared all the cache: Internet Options - General tab (Delete Cookies, Delete Files & Clear History).
I closed the Browser & restart it and tried the same. It is strange to see that when
I changed the names of different file to 'bp', and tried the results were same, erroneous.
I don't know what is the reason! But may be it is similar to try to create folder naming 'con',
which is a reserved
word and we can't create one with this name.
