Find Data is broken for time based data (at least)

Find Data is broken for time based data (at least). Here is what I see:

• Master (Sept 1), Linux, builtin server.

• can.exo. Apply.

• Lets paint by Solid Color. Wireframe. Now we can see what is going on.

• Find Data. Data Producer: can.exo. "accl (Mag)" - "is max". "Find Data". This works. It will find a point on the edge of the block.

• Move forward one timestep. Two things to notice. 1) The "Selection Criteria" has changed to "id is", with no data selected and 2) nothing is selected (which makes sense).

• For this timestep, timestep 1, reset "Selection Criteria" to be "accl (Mag)" - "is max".
  The point appears again. Now, as we move forward in time, it appears to work.

My guess is that ParaView is messing up transferring the selection between blocks.
