Update uploaded executable

Hi there,

I am using filr and it is super fine. But I encountered a problem, and I am not sure how to solve it. I upload binaries (exe) of my software and I sometimes want to update them. But when I do so, the exe gets uploaded, then I press update on the right side of the post and then the newly uploaded file disappears. I set ALLOW_UNFILTERED_UPLOADS to true, so it should not beeing blocked.

Do you have any ideas, what is going wrong?

Thanks you very much!
Stephan
