Unfortunately, I don't have a lot of detail at this time, but one of my clients has been having a world of grief with the auto-block functionality on their ION. Sometimes, the auto-block will seem correct, and correctly show that a prior edit is being prevented from tracking through a following cue, but other times, it will cause the entire cue stack to basically lockup. You can hit Go/Back, and see the cues supposedly run on screen, but what is output never changes. Sometimes, a quick run forward through the stack past the block and then backing up over it will restore the console to normal operation, and other times, they need to reenter the cue with the block to get rid of the block. I can see an auto-block holding single channels (and indeed, that is all that is seen on the display) but this is holding entire cues, despite only single channel edits . . .
Frankly, auto-block seems like it should be a optional feature - good programming practice and attentiveness would tend to indicate that it is not necessary for all users. Having said that, a short term solution to the problem would be to be able to simply turn the feature off, and deal with tracking changes manually.
Otherwise, has anyone seen any behaviour of this type? I think we first noticed it on 1.8.0 (maybe 1.7 . . ) and it is still present in 1.8.2 . . . I will try to see if I can find a scenario to reliably duplicate what they have been seeing, but to date, it has happened primarily when I have not been on site . . .
