7.0.2 RC1 Crashes and Corrupts Stack Files

[Ray]

On my Windows 8.1 system I do the following:

    1)  create a new main stack
    2)  drag a player object onto it
    3)  remove the default fileName (source)
    4)  save the stack file

At this point I get "Livecode has stopped working".  With no other 
options I close the program and find my entire stack file has been 
corrupted and will not re-open.

Anybody know anything about this?
