crash with montage (solved)

I just installed WL6 on a new hard drive with Vista 32bit. Every time I try to open a montage WL6 just “puffs”, no error message. I just do: open - montage - and it’s gone.
If I initiate a new one it works until I try to insert a file. At that point it crashes, it disappears without any error message.

I have been using WL6 on another hard drive with Vista32, same machine, no problems at all, for years!
Somebody has any idea what could it be?
Any help appreciated.

Solved. Re-installed WL6 and now it seems to work fine.
