I am often getting a java socket timeout on Josm start up and it results in the image preferences being lost. They do not return if I am then able to start normally without the error message.
Thanks for the imagery preferences fix.
I increased the socket.timeout.connect to 150 and socket.timeout.read to 300 recently for another reason (to upload a large changeset) but it didn’t seem to affect the Java_timeout problem, though the Java problem has begun since I changed those settings I think, so I will try setting them back to the default and see if it affects the problem.
