Applay "Enter" operation to most objects cause RedBox (as in issue
#145) with application Freeze (for short RBF).
For attached save it reproducible for me:
press 'y', 'u', Enter key (i.e. call "Enter" on self square) - cause RBF;
press 'y', 'u', select fountain, Enter key, select fountain or floor - cause RBF.
If needed, I can prepare minidump, as described for issue
