Steps to reproduce:

Observed result:

Construct 2 stops responding / crashes

Expected result:

dunno

Browsers affected:

unrelated

Operating system & service pack:

win 8.1 64bit checked

This works fine for me in 152 on windows 7 64 bit

Can only reproduce when double-clicking, not just clicking. Should be fixed in the next build.
