Just tried the linux-64 version. I could see the templates, but then closed the program, opened it again, and the templates are all red crosses. So deleted the directory and this seems reproducible:

1. Start LDCad, select the LDraw directory, select the templates bin (no need to select "new" or "open"). The templates appear.
2. Close LDCad.
3. Start LDCad, select the templates bin. Just red crosses.

I'd say there's something wrong either in my system or in the default path for the templates. More investigation reveals that:

4. Close LDCad. Delete config/templates.inv.
5. Start LDCad, select the templates bin. The templates appear again.

The paths in templates.inv look OK, though.
