TRAY STEEL  If you want to remove support for all other languages accept English then just use the following command in the Terminal. You will need to supply admin password.

(Version 1.3.9)

TRAY STEEL  QT 7.4.1 & Perian 1.1 = subtitles again. Hoorah!  
(Version 1.1)

TRAY STEEL  This is the last of the apps I use to be made Leopard proof and it was worth the wait. I now use Time Machine to backup my data partitions and SuperDuper! to make a clone of my OS X partition after booting into a USB flash drive. Have been using CCC but much prefer SuperDuper!

Tested and all works fine for me. Kudos to the developer for all his hard work and a free upgrade too!  
(Version 2.5)

TRAY STEEL  Just installed iScroll2 0.30 and it now keeps my settings. Well done works great!  
(Version 0.30)

TRAY STEEL  iScroll 0.29 works on Leopard but has a small bug of not saving your settings upon reboot. To get round this you can manually edit the default settings file /Library/Preferences/name.razzfazz.driver.iScroll2 using texteditor/BBEdit to reflect the settings you want.
