Devs: please include this update in Arduino 0018. The enhanced rxtx solves one of the most annoying problems I've run into in the Arduino IDE. If you have any sleeping Bluetooth SPP devices, the default Arduino IDE will take a long time to load, and then a long time to open the Tools menu every time.
In addition, your sleeping Bluetooth SPP connections are trashed. The old rxtx somehow sits on them and prevents them from being used by other applications. Just by opening the Arduino IDE once, you now have to reset multiple Bluetooth devices, or unpair/repair them.
The new rxtx dll above fixes that issue completely.
Yes, yes, yes, please add this to 0018! The difference is dramatic! My startup goes from a little below 1 minute to only several seconds. Opening the tools menu even took me two minutes (no joke) and now it shows immediately.

I have also problems with my arduino17 on a vista pc. I would try this fix, but cannot open the rar file.
Can anybody give me a hint, how to open this file,
Thank's
Third party programs that can only read (unpack) RAR files include: WinZip (Windows), 7-Zip (multiplatform), IZArc (Windows), PeaZip (Windows, Linux), Zipeg (Windows, Mac OS X), ALZip (Windows), along with the free version of unrar (which is available for Linux and FreeBSD). Mac OS X readers include Stuffit Expander, The Unarchiver and Zipeg. Stuffit Expander is also available for Mac OS Classic with RAR support for this platform.
If you go to the second link above, all those third party programs have their own links. I'm too lazy on a Saturday to copy the links into this reply.
Another big thanks for fixing this problem. I have an older laptop running XP, and the arduino application was completely unusable due to the delays in the 0018 distribution DLL.
Your modified DLL fixed the entire problem, instantly.
I will try to look for it. But you can build your own patched version. First look the point 7 of this document, ignore the text, just copy the "serial_test" function code.
Hey all, i just got my UNO yesterday and noticed the delay on the IDE soft and i can tell that this fix worked for the 0021, too(i had BT com port working on my laptop). thanks!
I have the same problem with the slow Arduino IDE. I'm new at this and don't yet know Java. When I look at the Arduino\Lib directory there are only *.jar files. I do not know what to do with your *.rar file. Could you please give more detailed instructions for us Java newbies. Gracias in advance.

My bad. I downloaded 7-zip to unzip your *rar file and replaced the rxtxSerial.dll iin the Arduino directory.
However, there seems to be no change in the excessive compile time using the arduino IDE. I am using windows 8.1. Any thoughts and suggestions?
