If you have tried the refresh button of your browser (which one do you use) and that doesn't work, clear the browser cache (Temporary Internet Files).
There are times as I have said when an image can't be displayed because a server is busy. It is best to try again later.
Thanks again David R, I have tried as You sayed [refresh button ( there is only one I can use, I think) and clear the browser cache]
Below I tried to copy an example of what I want to say
with an by me typed cross that also could not be copied.
"FilterMgr 0 x Not supported yet! Care! Future feature for Standard Shield with XP SP2."
I hope that I clearly explained the problem, because I do not know much of the English language.
