Sorry if this has been answered before, but I couldn't find a thread on it.

In create-a-style, if you try to change an object that is cc and hasn't been made with channels (possibly?),or is otherwise not recolorable, you get an "Invalid Style" message.

Usually, if I've clicked that object directly, I'm able to exit. But if I was dragging a palette onto the object, I'm stuck. I get a flashing orange arrow pointing to the style, and I can't close the palette or click anything, which is a big pain when I've been redecorating a whole room.

Of course, now that I know that object is messed up, I won't do that again, but is there any way to break out of that process and return to the game without shutting down the game and starting over?

Is it frozen that none of the keyboard shortcut keys work? ESC, F1, F2...etc? Can you bring up the cheat console?
I'm usually able to click the "X" to close the CAST tool window even after it seems to hang, just that it takes a while to respond.

In this instance, I couldn't click the X, and ESC, Break, Bkspce, etc. didn't work. I was hoping there'd be some key combination I could use - I didn't think to try opening the console. I might bring up that object again and see if I can open the console, and then... is there a console break command?

Chances are, if you were unable to do the other commands, you would not have been able to open the console either.
Is this a cc item? what is it and where is it? I might have a look at this for testing. Have you discovered this issue
with any other items?

Yes, but they're not MTS items, mostly things other people have passed on to me, like StylistSims clothing (beware!). In this case, it was a cute dollhouse from a Russian site. Here's the download.

I realize it's my own d*mn fault for getting stuff from questionable places, but I'm still curious about why these aren't recolorable. In this case, I was dragging the palette from a toy box onto the dollhouse, not entering create a style from the dollhouse.
