Max, right now I'm on a 2 week break with my kid. I'll be able to take a
closer look at this next week.
I see now that I should have provided an easy possibility to revert back
to a previous version of WireframeSketcher. This would give you a
temporary solution. Right now the only way to go back is to install the
previous version manually. If you think you are savvy enough to do it
then you can get it here:
