This is on windows 7 pro x64 using java 6 32-bit, with all updates and default settings.

"This crash happens whether or not a download OSM data first."

"This crash happens whether or not I download OSM data first."

Ok, if I uninstall JOSM, then delete the JOSM file in C:\Users\user\AppData\Roaming then re-install with the .exe it all works fine.
