Also known as "Text Services Manager Fix". The operating system give low-level programmers a mechanism (called the jGNEFilter) for intercepting user events (mouse clicks, key downs, etc) and "filtering" or modifying them before the computer processes them. Many system extensions use this hook to implement special functionality in your computer (such as SuperClock and ObiWan) and work transparently to the user. This system extension remedies the problem by checking events as they are presented to the running programs. If an event has not passed through the installed filters, this extension sends it to be filtered before returning. In plain English this means that button clicks are better understood by the computer and fewer 'missing' button clicks will occur. Use by program like SpellTools to make certain that all button clicks addressed to it are properly recognized.
