RXTXSerial and Bluetooth Serial Ports

My Arduino software had been taking about 5 minutes to start up and then once it was loaded would lockup near enough instantly. After quite a lot of playing around it seems that the RXTX library,used by the software, doesn't like Bluetooth COM ports. I had about 5 virtual COM ports showing in my device manager and once these were removed the Arduino software was back up and running.

Just thought I would post this in case anyone else comes across similar problems.


This is in the troubleshooting guide, but I think it's difficult to find: http://www.arduino.cc/en/Guide/Troubleshooting#toc11

If anyone has thoughts on making that page easier to find / better, let me know, as I hate to have lots of people having to rediscover the solutions to the same problems.

I notice that at the top of this forum is a link to the main arduino site, maybe you could add some links there to the playground, trouble shooting and other relevent links.
