Hi,
I know it is not very precise question, but do you have any idea why drop zone functionality might not work for FileUpload?
I just upgraded to 3.3.0 and put this on page to test how this works:

<UFileUpload accept="image/*"></UFileUpload>

1. when I hover over the component it changes background. OK
2. when I click on it it opens system file dialog, OK
3. but when I try to drop image from my desktop - nothing happens (it is just opened in new tab) :-(

Should I install some other software besides v.3.3.0 to make it work?
What possibly might be the cause? I would appreciate any ideas...
