I assume if the program is quitting on you, you are in MacOS 9. I've tried it in both 9 and X and only 9 had issues. They were quickly solved by allocating more RAM to the software. Double it and you should find it runs just fine.

The software works for me. It has minor issues, but overall it works well. It's the only non-commercial Texas Hold'Em that I've found, so right now it's top of the heap. If anyone knows of better, feel free to post the info here.
