I don't know if you already have tested the 2007er version with vista, but on my computer it crashes alot. The old one runs without problems. Maybe it's just on my computer, but I guess it wouldn't be bad to test it out since nearly all new computers are preinstalled with vista now.
For example it crashes wenn I want to translate a word
We develop Stackz on Vista, and run all the internal tests on Vista.
Many of the testers are using Vista, and it runs fine on their system as well.
Maybe something with your dictionary configuration is wrong if it crashes when "translating a word" - I guess you refer to the dictionary tool there?
Please describe in detail what you do to reproduce a crash.
I'm sorry, there was a problem with the dictionary.
Now everything works fine. Keep up the good work!
