XF 1.1 Upload file process

[Morgain]

When I try to upload a file on any XF forums - my own which are either 1.15 or 1.2 - and here - I can call the dialogue and browse to the file.
But then the dialogue box either hangs or it switches to "No file selected."

If I click Close, and post, the post appears with the attachment on it.

I just started using a new laptop (Win7) so maybe I have a setting that isn't working well with XF.
I use Firefox and I have various addons to block ads.

Try disabling the browser add-ons, I suspect one of those is to blame.

Otherwise uncheck the flash uploader in your account preferences: http://xenforo.com/community/account/preferences
