I am experiencing a problem like this too, and it is reproducible for me. I'm playing the first crazy castle campaign, and I have had it freeze putting in different roller coasters in different locations. I can repeat it when attempting to place the collusus 1 roller coaster as shown in the very top corner, and then moving it towards the water. I actually think it is time based though, ie if it takes over a minute to place the ride (trying to find best location), then it freezes. When it freezes, the mouse icon also changes to a Zzzzz icon. I don't know if this is relevant?
