I have succesfully used the Image Uploader in 2.5 since I upgraded but suddenly this morning it doesn't work!
I have tried it with both Firefox and IE and with two computers.
I have tried to upload new WP files (deleting the existing first) but no luck.
This is the problem:
When I upload, it seems like the image is being uploaded, it says "crunching" immediately but then I get a login window inside the upload window!
I have uploaded a screendump for you too see here:
Anyone know how to fix this?
