NX NX ignores the Windows double-click speed setting at slowest.

Adjusting the double-click speed setting in Windows has no effect on what NX considers a double-click. This is an important setting for people with fine motor disability.

Since NX12, selection no longer uses the system double click speed in the graphics window.  Instead, we use a hardcoded double click delay value of 180 msecs.  This is generally sufficient for most users.  If the user prefers to use the system double click delay, we have an environment variable to revert back to the old behavior.
