Yes. I was wrong. I just installed Fish Tycoon on my new Mac Pro yesterday. I tried twice to use window mode on my Mac Pro and the screen went black then returned as full screen. I don't remember now whether I tried on the PowerBook, but I haven't used the PB for games for many months. I tried again after reading your post and now I have a tiny little window to play in. I suppose there is no Universal Binary or support for a window size between tiny and fullscreen? ;-)
I have the Mac version 1.00 build 1. I didn't see any info about the current versions on the LDW site for Mac or PC. I'll go check again in case I missed it somewhere.
Thanks very much for your reply. Hope to hear from Carla or someone soon from my support request you pointed me to.
