ARGH! All connections lost!!!
Wow, that’s a BIG bug! I managed to get Max5.1.0 into a state where no connections could be made anymore, and then, in any loaded patch, almost all connections were lost (except a few and signal)!
Hide/Show Connections was not part of it, of course. After throwing away the preferences folder, everything is fine again, but it is still freaky!
How I got there? I was undoing/redoing in a subpatcher a lot, then suddenly no connections could be made anymore, so I saved and quit.
Now I discovered that the above bug has a consequence in the patch saved when Max was in connection limbo (attached for testing): Trying to de-encapsulate [p add-std] within [p sequence-descriptors] crashes:
