I have loaded the arduino SW for the uno on my old laptop win xp (32 bit, service back 3) and when I execute the program, all of the pull-down menus are blank. I also installed a fresh java , but to no avail. When I installed the same SW on my new laptop (win7, 64 bit), it works fine. I know what you may be thinking, but I really want it to work on my old laptop. I could not find an issue like this in the "troubleshooting" section. Thanks for your help, Larry Stemke
Very weird. Can you try an older version of the IDE, like 0023? It's a long shot but might shed some light.
