[SR-Users] Possible conflict between t_newtran and setflag for ACC

[Patrick Wakano]

Thanks for your reply Henning!

I also removed it from my script.
The only thing is that when using it there is this nasty side effect, so I
think if the function is meaningless it can be removed.
I will create a ticket for it, so it can be evaluated what is the best
approach.

Thank you,
Kind regards,
Patrick Wakano
