I tried to recreate those problems and the only thing that I found wrong is that the target for audio behavior on intersections wont stick meaning I have to reselect the target. Other then that I managed to make a sample app :
303 - Intersection sample.zip

After you download the latest version, did you uninstall the previous version before installing the new one?

Try restarting your PC, that should solve the problem.

Try deleting that frame element from builder , remove the frames from the builder folder and try importing them again. If this is not working make sure that the names for the rest of 6 frames are named correctly and if this still doesn't work then I suggest sending those frames to alin@interactstudios.com so we can have a look at them to find what it's wrong with them.

To drag the frames in the correct order you order them like: 001, 002,003... select all and you start dragging from frame 001. So with all of them selected drag them into the builder by performing the drag action to the first frame.
For the second problem try to delete that frame element, remove the frames from the builder folder and try importing them again.

We found the problem and a fix will apear as soon as possible. Thank you for your feedback.

Could you tell us what behaviors you have on that page?

Is this sample app not working for you?:
276 - Scale behavior.zip
