The prepan.org server seems to be out of action about half the times I try it.
Ever so that? I haven't feel so often PrePAN was down...
It seemed to be going down a lot. Anyway I will close this issue.
The problem is that the file http://prepan.org/css/prepan.css never finishes loading. It starts loading and then the end of the file is never seen.
This problem only happens on Windows computers. I have tried it on two different Windows computers (Vista and Windows 7) and in either case the page never loads fully. I have used Google Chrome and Firefox browsers on both computers and in both cases the same problem of the page never loading occurred.
Just to clarify, here is a screen shot of the "Developer tools" for http://prepan.org as it tries to load http://prepan.org/ on a Windows computer:
As you can see it takes three minutes to try to load this CSS file then finally gives up.
This seems to be working OK now.
