I'm not sure if i'm understanding you correctly, (please explain further if i'm not) but they are working fine for me.
-When i click on favorites and join a channel (yes,you can only do one at a time) it opens the channel i pick. With that channel still open, i reopen favorites, i pick another channel, click and it opens fine.
-When i click on tools>script editor it opens remotes and the first script in my list is open in the window, While there, i clicked view and opened one halfway down the list, closed remotes. Clicked on tools>script editor and remotes opened with the last script i had open present in the window.
