Image Upload 'logs out' after uploading

Hi,

I recently upgraded from 1.3.3 to 1.3.4. After this i had some problems with the admin screen; whenever I left the admin tab to go to another tab and then returned, it logged me out when i clicked a link. Rightly or wrongly I got round this by copying the php.ini file into the admin directory and it worked great.

I think this same issue is affecting my uploading of images though.

I can upload a main product image with no problems - however when I try to upload in image with ckeditor, the picture uploads; but when I try to save the page, it prompts me to log back in again. Of course, it doesn't save the page.

I tried copying the php.ini file into the ckeditor folder but that didn't work - can somebody help?

Thank you in advance....
