no worries; beta testing is there to find all sorts of problems. :)

Incidentally, Phil, I restored windows from a disk image, and it resolved the issue, although hair simulation wouldn't work.

So I reverted to an older version of VWD.

Will see what happens now.

If the program can't find VWD, it asks us to locate it.

Is it possilbe we could have access to that path so we can manually change it? Being able to use two versions of VWD might be useful, and in this case would be. The alternative is to change the folder name, which works well enough, but just seems inelegant. :)
