Hi,

I made a post here a couple of weeks ago describing a problem that some of our clients were experiencing when attempting to upload images. If they try to upload images (using core Image field) in Internet Explorer 10, they get a white screen when they click Upload.

I have done a little bit more digging and found that this issue only occurs when the Shadowbox module is enabled. If I have shadowbox module turned on, uploading images causes a white screen. If the module is turned off, images can be uploaded as expected.

To recreate the problem, follow the steps below:

1) Fresh install of Drupal
2) Enable the following modules: Field UI, File, Image
3) Create a content type called Page with a single Image upload field
4) In Internet Explorer 10, go to node/add and select an image in the upload field
5) Click the upload button beside the field (not the save button at the bottom). The image gets uploaded correctly.
6) Now, enable the Shadowbox module (7.x-3.0-rc2, 7.x-4.0-rc1 or 7.x-4.x-dev) and use the latest version of shadowbox (3.0.3)
7) Repeat steps 4 and 5. This time, when you click upload, you will get a white screen with no error messages.

Even though in the Shadowbox settings page I have "Page specific activation settings" that should stop Shadowbox being enabled on node/add/*, this problem still occurs.
