In Geneforge 2 (on my Windows) the text was spilling out of windows and either overwriting other text or disappearing. Still playable, but ugly. I reported it several years ago, but to no effect.
To my dissmay Geneforge 3 had exactly the same problem.
Geneforge 4 seems to be cured! I only tried the demo for a few minutes, but I hope I am right. Congratulations! Hehe, maybe I will even buy it now.
