I was looking at this timer for a possible use in a different situation. If I understand correctly how this timer is working, there is a possibility of extending the first timer out to almost double what it is supposed to run.

T1 is added with a time of 20 seconds.
19 seconds later T2 is added for 25 seconds.
The list gets sorted and timer T1 is first in the list with a 20 second time.
T1 runs for a total of 39 seconds.

The add timer function does not update and compensate for elapsed time is what I am thinking.

Currently a work around for waiting to rez props in a SATMSG/NOTSATMSG is to call a notecard to do the work. Would be nice to be able to rez/derez props directly via SATMSG/NOTSATMSG.

[12:38] Howard Baxton: Looking at the V3 NOT/SATMSG handler and there's a situation in IW I've been working on which has unfolded where V2 can't handle the situation when noting in the pose changes except props and notecard name. Since I've implemented the addition of notecard name into the slots list there, I can now add the condition where notecard name changes but everything about the pose stays the same... if(listsEqual == FALSE || oldCardName != newCardName). V3 is enough different that there is no place for this line but it should be added in as a check. SATMSG really only needs to know when notecard name changes but NOTSAT really needs to know both conditions.
[12:39] Howard Baxton: ((well I think that's true about SATMSG))

This is new behavior in V4.00. I've verified that ON_UNSIT does not fire in V3.10 when changing seats. I've not gone further into seeing what can be done (if anything should be done) to correct this issue.

This one caught me off guard today in class as I was not expecting a change seats to fire the ON_UNSIT.
