Hi Simon,
we found on the latest version of November a Bug in the Era random.
By moving the buttons with the command at times is moved but can no longer delete and the command does not exist, I'll explain:
I create a button
Check command
I press OK and the scene when pressed starts.
I want to move
I hold I press CTRL and place the button in the new position
Release the CTRL key and the key when pressed does the scene.
If I go with the mouse in the old location (where now there is nothing) and I press the mouse part of the scene.
It would seem that the BUG does not always happen, happens every now and no longer èpossibile camcellarlo, if we forget to save every time we lose all the positions that we have performed before the accident.
I WAS very good on the screen, especially in theater.
