Sorry -forgot to read the first bit.

If altering the TMD in realtime, then it must remain
attached to a GsDOBJ2 to remain being drawn etc;
the trouble with altering it while drawing it is that
the drawing goes on in the background, hence you are liable
to get problems when it's drawing something that you are in the 
process of overwriting, ie a temporarily-invalid structure.
Make sure you only change it at certain points to avoid this.

Having said that, the 'blow' demo does runtime TMD alteration
without troubles.
