Card Vertical Scrollbars

Pete,

I'd seriously consider "reconsidering" your design concept. The speed with which LC goes to new cards makes the use of scrolling anything other than a text field not a very plausible solution. A really good navigation concept that judiciously provides connections between associated and related answers/solutions/queries makes for something far more useful in an application than interminable "scrolling" gobs of "things" that the user has to scrutinize in order to proceed with whatever it is they are doing or trying to do. A well thought-out application resolves all of these issues for the user. These are decisions that you should be making "for" the user; not just slapping up a lot of information/data that they have to process. You should do the processing. You're the expert of your application. Obviously, I'm not talking about applications designed for the purpose of the user creating content. They should just be providing information that allows your application to make decisions for alternatives in processing; otherwise, there is no point in your creating the application in the first place.

Frankly, I'm also against the entire concept of allowing the resizing of windows. When we were dealing with 9" and 12" screens, that was obligatory. Not so now. Obviously, IMHO! 

Now, off of my soap-box! (smile) Good luck.

You need to do that because the locked group (it must be locked) will not change size automatically, it has to be told to fit the window. If the group's contents exceed the group's size, the scrollbars will activate automatically. If the group is large enough to accomodate all its contents, scrollbars will disable automatically.
