[TYPO3] Warnings and kick upon simple modification

[Tobias Jonch]

Hello :-)

I've only just recently got Typo3 up and running, and I'm receiving a
lot of warnings. Whether I'm trying to edit the default page or create
a new, I seem to get the same warnings when I get to the page where I
put in the actual text (regular text field type of element):

Warning: fopen(C:/Program Files

Also, if I ignore the warnings and try to save the page, I'm told that
my session has expired and asked whether I want to log in again (and
that doesn't seem to work).

Does these warnings sound familiar to anyone?

Thanks,
Tobias

PS: I'm on a vista64, which is rather anal about permissions. Could that be it?
