In this case, a customer couldn’t start Softimage again after he crashed while editing a layout.
When he started Softimage, it went into the layout editing mode and stopped responding.
In the past, we’ve fixed problems like this by asking customers to rename the User folder, or to delete any bogus .xsily files (for example, zero-length files) from the Application\layouts folder in their User location.
However, I learned from Luc-Eric that there’s a specific preference that specifies whether Softimage is in the layout editing mode. So, to stop Softimage from starting up in the Layout Editor, we had to edit %XSI_USERHOME%\Data\Preferences\default.xsipref and change this
xsiprivate.UI_LAYOUT_DEFAULT = Layout Editor
xsiprivate.UI_LAYOUT_DEFAULT = Default
