I had to tell you, I searched for "Winshow.dll" on my C:\
drive, but could not find any. The page
(http://doxdesk.com/parasite/Winshow.html)recommended
me to delete this file, but i could not find it..
So, I downloaded the "HijackThis" program, launched it,
and this program found (among others) the "Winshow.dll"
under "..\Documents and setting\user\applications\ and
voila; there was a folder called Winshow. I deleted the
file winshow.dll, and launched IE6 without problems.
This is a common problem with Windows XP.
Everyone of my friends who's using XP
experienced the same problem before.
Microsoft hasn't got a solution yet.
