I am having the same problem, only my file is 23MB. Any news on this issue?

I'm disheartened that no-one has replied to this yet, but as you say it isnt something most people are effected by. I have the same problem as you.

on FA the flash file respects the resolution but here it stretches to fill the entire screen which looks rather bad.

Disregard, i suppose it was just slow. :)

It shows up in the gallery now as well, but only for one out of two submissions.

I was able to upload thumbnails today, which are visible in my feed now, but the "gallery" entries are still blank as if there is no thumbnail. Is it a cache thing?

I have the same problem, using the same browser. I cannot upload a thumbnail.
