Tried using this tool today for the first time but the content panel isn't showing and instead there's a blue bracketed number next to the collector tool icon which goes up in number as new content gets selected. Know I'm missing something here, but can't see anything under Preferences nor under View>Extras>Hide/Show content grabber which, anyway, I've tried both to no avail.
Cheers John. It was Preferences. Now deleted and the CCT works just fine. Too often I think it's me doing something wrong or failing to understand a new feature – new to me that is, as I hadn't ever used it.
