[ptx] WinX control points crash

[Scott Reed]

I am now running the latest WinX snapshot that Pablo just completed. It 
fixed the Remove image problem but it is crashing when I select control 
points. I am selecting two points per image pair and on the third pair, 
it crashes on the second point. It tells me it is writing a log file. I 
don't see the file, but if I could find it, would anyone be interested 
in it's contents?
