--- Comment #3 from Alan_H a.herron@telus.net 2011-03-07 11:25:04 CST --- Re using Direct3D, I really don't know. It isn't conspicuous. I'm a user of the program, not a developer, so I don't have inside knowledge. All I can say is this is where the regression testing led me. I'm a newbie using regression testing, so the process might have gone off track without my realizing it.
To trigger the error I simply start Future Tax (FT) and try to "Open an existing file" (which I have). I immediately get an "unsupported operation" error pop up window that leads to a subsequent crash when it is acknowledged. No problems arise under wine 1.0.1
The display is a scrollable graphical, colored interactive income tax form in a windowed arrangement that looks just like the paper versions of the income tax forms. They might have used layering to cope with the nested structure of the forms arrangement.
Hope this helps.
