fix file saving bugs+discussion

I just ahd to click "Submit" twice to upload a file on johnabbe -- http://johnabbe.wagn.org/wagn/basic_trust+attachment

Tested the same arrangement on another card and then it worked, so shrug.

I tried a few more and didn't have a problem. Might have been an unrelated server issue...
