I got that with the first DWT sample I tried too using 1.039 too.  37
sec seems about right for how long it took to error out.
That one was tree\Snippet15 I think.
Then I tried the treeeditor one, and was taking a long time so I killed it.

Yes I'm sure I've got oneatatime off.  All I'm doing to switch DMD
configs is to unzip the new DMD files on top of the old installation,
and run my "usetango.bat" script to fix it up after that.

That script definitely isn't smart enough to do something different
based on the current version of DMD installed.  So I'm positive that
I'm using the same DSSS config for 1.037/1.038/1.039.
