[FLASH-USERS] how to force refinement

[Slavin, Jonathan]

Hi Klaus,

I think you may be right. I had thought that by using gr_lrefineMaxByTime
and setting a higher value of for gr_lrefmaxTimeValue (i.e. a higher value
than the initial one) that the value of lrefine_max would be increased.
However that seems not to be happening. I've used gr_lrefineMaxByTime in
the past to decrease the maximum refinement, but it seems that it doesn't
work in the opposite direction.
I'm not sure what happens to lrefine_max, but when I print it out, I got
some odd value (I printed with format i5 and got ****. Of course I could've
printed it with default formatting.)

Regards,
Jon
