Hello Jack,
TW 7 is just simply not stable enough with all it's bugs. Forum members have posted plenty of bug fix and improvement requests, a lot going unanswered!
When will we see a fixed version of TW 7?
I like many who have paid for this product would like to use it to build professional tours but I still have to revert back to an earlier version to do so.
Regards,
Paul.
