As the title suggests the 'from your computer' feature on UploadField has stopped working...

I am able to click it and have it open the file system but when selecting an image either by double clicking it or hitting open nothing happens.

What could be the reason for this? Permissions everywhere have remained the same. It used to work fine and the 'from files' still works I'm just unable to upload anything from the computer.

How would I resolve this?

Oh, just to add that when dragging and dropping an image it works and uploads just fine. It's literally the 'from your computer' bit that isn't doing anything
