Hi Aaron,
thank you for your reply. I’ll try that later. Perhaps I should consider
having a separate dynamics variable in the long run though. Potential
issues like this could be so avoided by simply changing the problematic
line of code. That would also allow me to have both the “normal” dynamics
and the vertical aligned ones as needed, as suggested by other members in
my other threads.
Cheers
Martín.
