Protip: The scaler in the PC version is incompatible with many current graphics card drivers. If you want to play the PC version in full screen, change your desktop resolution to something with a 4:3 aspect ratio (like 1024x768) or the game will look like a mess.
Sadly, the majority of Popcap's games (i.e. all the ones that use the same old version of their "SexyApp" framework) suffer from the same problem. It's really quite baffling that they have never bothered to fix the problem, even when they hadn't been bought out by EA. It's like they're more interested in self-promotion than supporting their products.
