Version 5.3.0.1-signed 100.5 kB Works with Firefox 3.0 and later, SeaMonkey 2.0 and later

New in Version 5.3.0:

The bug triggered a 0-byte ghost file to appear under certain circumstances.

Fixed:
-Extremely rare case of empty menu caused by lack of DASH format info despite indication
-Rare case of MP3 file name collision for long conversion jobs: for long input files, the time FFmpeg takes to scan the input (renamed to *.tmp) and start writing the output file can be substantial, which opened the door for CYS to create another MP3 File with the same name, ultimately colliding with the 1st
-Iconic menu conflicts caused by non-specific CSS code

Changed:
