thejfk,
It sounds as if you have one of the newer WS467's produced after early '07. These units have "soft start" and a number of other new features.
Puck is correct that these units will not activate in response to a bright or dim command. The option change that you made forces AHP to issue and "ON" command in place of a "Bright 100%" command sequence for simple ON operation. Unfortunately, this option doesn't apply to absolute bright/dim commands within a macro.
For example, a Turn on and Dim 50% macro will send the following commands (view in activity monitor).
Event Date/Time Action Data
0 10/05/2008 8:57:50 am Receive RF L14 On
1 10/05/2008 8:57:56 am Macro A12 (New Module)
2 10/05/2008 8:57:56 am Macro
A Bright 100(New Module)3 10/05/2008 8:57:56 am Macro A Dim 50(New Module)
Notice from the above that AHP is again sending the "bright 100%" command to turn on your WS467. This will not work with the newer units.
The solution is to re-identify your WS467 as a LM14a 2-way lamp module within AHP. This will force AHP to use a different set of commands referred to as "Extended Codes".
Please give this a try and let us know how things are going,
