Anyone had problems with S7-Graph v5.1? I've had a occasionally recurring problem where I get 2 step outputs (N "Sequence_Step_xx") on simultaneously. Casues my sequence to do some very strange things, and naturally, Siemens claim there isn't a problem.

I am sure it isn't the "Too much information to be displayed" problem, as tracing the bits back through the rest of the software shows both coils/bits to be ON. Bits are not used anywhere else in the system (by word/byte either).
