It works perfectly. Thanks!
By the way, when I load/save my schematic, and when I place a component from a library, the dialog box remembers the directory from where I did the last place component or load/save schematic. Usually the libraries are in one place and the schematics somewhere completely different. I see there is a button "Libs" to jump to the libraries which is nice. Perhaps I am using it wrongly but when I load/save schematics, I spend a bit of time navigating back to the directory where my schematics are. Unless there is already a better way to do it, perhaps it would be nice to have another button to jump to where my schematics are, and though I'm not sure the best way to determine this path, perhaps you could use the directory where xschem was started.
