--- Comment #4 from Chiitoo escomk3@hotmail.com --- Forgot to add for the future when one goes and tries with Windows 7 mode selected: it will still crash, should the FFXI-window become lowered/inactive (via alt-tabbing for example).
This only happens if the opening movie is enabled though, via the configuration utility (which it by default is, and which doesn't quite work yet without gstreamer support, and still upside down and mirrored from left to right).
It can be mended by using native msctf.dll or by disabling the opening movie altogether via the configuration utility.
This is all documented on the FFXI-AppDB article.
