8536	LiveGPS is unreliable on my laptop	anonymous	team	"What steps will reproduce the problem?
 1. Select LiveGPS in prefs, select OK, continue through 'restart JOSM dialog, quit JOSM
 2. Restart JOSM with a data file; or, open a datafile from JOSM
 3. That's it, crashes almost every time.

What is the expected result? Live GPS working

What happens instead? Error dialog, LiveGPS disabled.

Please provide any additional information below. Attach a screenshot if
possible.

It's been like this for a long time. It still doesn't work. It's fine on my Desktop machine, same OS, same versions - Oh how useful!
