Helicon focus freezes while stacking large images

[Hendrik]

Dear forum,

I´m trying to stack several 39 megapixel photos (5412x7216 pixel). Unfortunately, Helicon Focus freezes and stops working. I can select the images and "Start", but then the freeze happens.

I´m using 5.1.29 with Win7, 64 bit and 8 gb memory.

I uploaded a sample stack at http://www.euerfotograf.de/ausgang/helicontest.zip (Attention, 9 mb download).
These images are stronger compressed than usual, I won´t even think about stacking TIFF files...

If I downsize them to 5000 px, stacking works fine - but that´s no solution...

Thanks, Hendrik
