For now, I'd either make less smartlists in a group or just try to not click on the group.
Not the best answer, but hopefully it isn't a deal breaker for you.
make less smartlists !!!
ur kidding right
smartlists are a fabulous feature of MC.
I was curious why the functionality to exclude child playlists was removed in 10.0. Admittedly i did not use it as intended cept to exclude child groups from being executed.
i played around and found a workaround.
when one drills down in the Playlists folder and selects any smartlist/playlist from a group, its selected with a red bar (thunderstorm). Now if u try to collapse that playlist group, there is no way to prevent all the smartlists/playlists in that group from being executed which can take ages yadda yada.
However, if u change focus from playlists, ( go to PN, CTRL+2), and then click back at the '+' to close the playlist group, it closes the group
without executing its child items.
Interestingly, when u drill down by clicking the + to open a playlist group there is no problem, its only when collapsing (pressing the +) of the same playlist group that it executes the child items.
i suppose if one were to click on the playlist group explicitly, then all items in it get executed...
but if one clicks the '+' , i prefer it not do so, as it implies opening/closing the folder.
just a thought, i can live with the above workaround.
