I've exported video clips many times without issues.
For some reason I can no longer specify export path, export preset or select output format from the Convert/Export window.

I can successfully export to MP4 with the default export path but I can't change the path or specify the format.

Mp4 is fine. I'm really interested in changing the export folder without resorting to editing the registry.
I know it's going to be something simple but I'm not seeing it.

Anyone have any ideas?

Thanks
