I have 3.1.4 on OpenSuse 12.2
Every time I start Xiphos it asks me Yes/No to make URL sword:// default to Xiphos.
When I click 'No' it does not remember because it happens at each start of Xiphos.
It remembers 'Yes'.
dates from 3.1.4; 3.1.5 has been out a long time, and 3.1.6 will be out within the week. re-file if it's a problem after 3.1.6 but i suspect this problem is gone.
