Here is the reg setting to un-grey the repeat field for reminders.
Code:
<characteristic type="HKCU\ControlPanel\Notifications\{15F11F90-8A5F-454c-89FC-BA9B7AAB0CAD}" translation="filesystem">
<parm name="Options" datatype="integer" value="1073741853"/>
</characteristic>
this was posted somewhere in the forums, I've since added to my kitchen.
*edit* here is where I found it....
