A brief look at the code tells me two things...

1. You are right, the default drawing is done first
and then the handler is called.

2. It will almost certainly not be changed in IBO3.6,
as such a change will be likely to break existing

I know that Jason has been working (in his spare time :-) on
significant modifications to the grid for IBO4. You may want to
suggest to him that he take a careful look at this aspect for the v4
release to see what can be done.

PS. In case you dont know, Jason is in Germany at the moment, not sure
exactly when he will be back on deck to answer this in more detail.

I was going to say HTH (hope this helps), but I know it doesn't.
