Steam – Is it possible to play Scrolls with the Steam Overlay

If you go your steam library and select "Add a game"->"Add a non-steam game" then find the executable for BF:BC2, this will show your friends when you are playing BC2. You will also be able to access the in-game overlay for PMing your steam friends and using the browser. Sadly, it won't show any details about the server you are on, just that you are playing it.

This is the best you can currently integrate non-steam games into steam (games that don't have a steam-activatable key, at least).

From helping others on Steam support forums and their result from following my suggestion, I have concluded the following as the cause:

Steam exits in an un-friendly way, thus not syncing your shortcuts with the cloud. This can occur when you let it (Steam) close by itself when shutting down/restarting your computer, Steam basically force closes, it does not close gracefully.

The main reason this is the cause is because Steam syncs your shortcuts with the cloud, but in order to do this it must shut down "gracefully". This means you have to shutdown Steam by doing:

Steam > Exit or Right-Click on Steam Icon Taskbar > Exit

Either of those will allow Steam to sync with the cloud if necessary.

Others say it is due to corruption of a local file, but it can be fixed by doing what I have suggested above. There hasn't been an official response from Steam on this issue, so it's just a logical guess based on past experiences of myself and others.
