 - Instead of falling back to your local charset, Aegisub will now use the "universalchardet" library (the one used by the Mozilla project) to autodetect the character set of non-Unicode files. (AMZ)
 - Added option to disable automatic grabbing of times from selected lines on the audio display. Also, it will never pick the times from 0:00:00.00 -> 0:00:00.00 lines. (AMZ)
 - Added a "Scale Border and Shadow" check box to script properties dialog. (AMZ)
+- Fixed drawing of inactive lines in audio display to prevent it from being drawn over selection. (AMZ)
