Hi Leonard.

Perhaps the problem is not with PowerHouse.  I have written lots of VBA programs to drive PowerHouse
and I have gotten the same problem (unknown iteration count, but the same incomplete screen draw)
before.  It was always due to trying to drive PowerHouse too fast.  Is your VBA code waiting for the
screen to update before it issues the next command?  I'd guess that's were the problem is.  You can get
pretty far ahead of PowerHouses' updates, but eventually you can choke it.

You can either use lockstep to look for a matchstring coming back in the data stream or you can use a
looping screen read to watch for a string to show up.  I have used both with equal success.  Also make
sure that the test for coming out of lockstep with each loop *really* makes sure the screen is finished
before proceeding.

You don't mention the 3rd party app you are testing, but if it is a human-interface then that's another
reason to make sure the screen is finished updating before running the next loop.
