Have you tried simply to reload the page clicking the button at the top of your browser?
Manchild solution should work for
all pages: reloading the page clears the cache
just for the F-1 Technical page.
Thanx, both of you. I had not the slightest idea why the icons changed colour.
BTW, why sometimes the (white) icons are small and sometimes big? I hope this is not a warning about the lenght of some posts (like mine)!
EDIT: duuhhhh.... the icons meaning is at the end of the forum page.... I am blind, I think.
