Windows 7 has something similar, but rather than blocking the app just tells you something like "This application has known problems on Windows 7" and gives you options to check for a fix online, or to run the application anyway (in most cases. there are a select few where it doesn't let you run them at all, but you still get a button to check for a solution).
Even if Apple sticks with blocking the application entirely (which in this particular case they're probably right to do so, as it would cause a kernel panic) it would be nice to put something actionable in the dialog.
Has automatically checking for a fix online ever worked? Admittedly I'm only an infrequent user of Windows, but I've never once had it actually do anything.
Yup! From Vista onwards the various incarnations of that started being more effective for me. In the case of incompatible programs it points you at the latest version of that program, if that fixes the problem. When applications crash and you send the report to Microsoft, I've had fixes come back in some cases including telling me to update a particular driver, or even giving me a Windows hotfix specific to that problem.
