Vanishing objects mystery

I have a serious problem, my objects keep on disappearing in the
frame editor! I wasn't running the frame or the application.

Here's what happening, I was editing objects in the frame editor,
and as soon as I clicked on one, five objects disappeared! I
couldn't restore them, I didn't highlight them, and didn't click
'delete' or anything!

Very soon, It deleted the whole frame, and I fear it will delete the whole application. can anyone help?

Sounds like a Virus to me, but I don't see why one would simply target MMF. Weird

First, what build of MMF2 do you use?

247.

You may want to update to the latest build 248----->
