Hello from France !
I had the same problem a few weeks ago, using the frog2 on a rock concert (4 MAC600,8 MAC250,...)
using at the same time UDF + Cue stack + direct orders on the program windows ... after about 10 minutes it' was like if the comand line was full and I could'nt do anythink else than clear everyting and relese my cue stacks before playing again...
It made that twice during the show...
It was the first time I had this problem, so I thought it my fault...doing somethings wrong ??
unfortunetly i did'nt save my show and can't send it to you... sory :cry:
I 'll tell you if I get this problem again ...
