Safari-Serious problem: Webkit2webprocess.exe -WINXP

[europanorama]

There is a serious problem with safari since over a year and apple seems not having found a solution. There are multiple consequences when webkit2webprocess.exe crashes. I tried some "solutions" without success in my case.
if you have safari pls check this site. Its showing a new html3 stereoviewer(photos only)

--------
everything is working fine until we go to FULL, fullsize-mode
use mouse or enter. esc to go back.
This is not working, error-message popping up:
webkit2webprocess.exe.
is solved when restarting safari.
in one discussion the say using an older version. i did, version 5.1 is the same but:
they say one has to remove/delete profile-directory. Where is it and how is it called?
deinstallation did not help eighter.
will provide link to a discussion a bit later.
btw: in opera no chance for Fullsize.
thanks a lot
