I've updated to the latest version of flash, I was on the latest before yesterday when the released a new one :)
The new version of the flash uploader caused the page to toss up two error messages before closing out. The error messages were the same, an exception has occurred.
I don't think the error is in the flash uploader. I believe that the problem is in a call to
local status,result = c_GetFileSize(_SESSION["username"],last_filename,nowdir)
on line 13 of uploadstat.html, do you know a way this could fail?
