Hi Ben,
To be rigorous, you'd also have to check whether that the
scriptExecutionStyle is not set to 9. Here's a handler that takes care of
that:
on mxTimeOut(me, aName, aPeriod, aHandler, aTarget, aStartTime) -------
-- INPUT: <aName> string name of timeOut object to create
-- <aPeriod> minimum time between callbacks, in milliseconds
-- <aHandler> symbol handler to call
-- <aTarget> object containing the callback handler
-- <aStartTime> value of milliseconds when first callback is
-- to be made
-- ACTION: Creates a new timeOut object, regardless of the version
-- Director (8.0 or greater).
-- If aStartTime is an integer, delays the first callback
-- until after the given time
-- OUTPUT: Returns a timeOut object.
--------------------------------------------------------------------
vVersion = getPlayerVersion()
if vVersion < 10 then
-- DMX or earlier
vTimeOut = timeOut(aName).new(aPeriod, aHandler, aTarget)
else if the scriptExecutionStyle = 9 then
-- DMX 2004 or later in DMX emulation mode
vTimeOut = timeOut(aName).new(aPeriod, aHandler, aTarget)
else
-- DMX 2004 or later
vTimeOut = timeOut().new(aName, aPeriod, aHandler, aTarget)
end if
if integerP(aStartTime) then
vTimeOut.time = aStartTime
end if
return vTimeOut
end mxTimeOut

Here's a version of your handler which:
* works with all versions of Director from 7.0
* performs no slower than yours on my Mac on all the versions of
Director that I tried it on (your mileage may vary)
* provides more precise version data
Enjoy,
James
