Here is the bugbase ticked: Bug#3940278 - [Windows] file.url throw error when application executable in root directory
If you launch AIR application packaged as bundle from root directory and try to get url property of any file you get IllegalOperationError.
No matter what file url property you try to get.
It's a big problem when you distribute your application on CD disks or flash drive.
I'd like to ask everyone affected by this issue to take a minute and vote for the following bug.
Thanks.
