[Bugs fixed]

• Reduced priority of ASF pseudo-handler to avoid interfering with input handlers that detect by filename.
• AVI: The preferred handler (fccHandler) field in the video stream is now ignored by default for consistency (unless re-enabled in preferences).

• UI: Select Range command is now disabled when no video is loaded.

• UI: The Configure and Cropping buttons in the filter list dialog no longer lose focus when clicked.
