my memory is a bit fuzzy on this so there may be one or two inaccuracies but the thrust of it is right;
I 'think' this is because of automatic delay compensation.
The 'fix' they gave was to just switch off additional outputs, as apparently no outputs is better than delayed outputs.
There was a dialogue when you first opened it mentioning such a problem with ok and cancel - ok actually implements this fix whereas cancel would have avoided it.
The only way I undid this 'fix' was to actually delete it from the registry (as uninstalling VC did not remove the entry). There may be a more elegant way to undo it, but if you know how to use registry editor then that certainly works - the dialogue then comes up again and you click cancel (or whatever the 'negative' option was...).
I don't remember if disabling automatic delay compensation also brings them back and I'm not in a position to test it.
Hope that helps...
