The following changes have been applied to the installer at
http://www.autohotkey.com/download/
Fixed hotstrings and the Input command on keyboard layouts that use AltGr to produce visible characters such as the @ symbol. [thanks Tekl, jordi, and /Torben]
Fixed WinGetText and ControlGetText so that the retrieved text is limited to the maximum size of a variable, which defaults to 64 MB. [thanks hermitress]
Slightly improved the monitoring and buffering of hotkeys (especially joystick) during times when the script is displaying a dialog or is uninterruptible.
Added directive
#MaxMem, which allows the maximum capacity of each variable to be changed from its default of 64 MB.
Added command
KeyWait, which waits for a key or mouse/joystick button to be released or pressed down.
