My application hangs when it is run on a Lenovo R60 laptop(Windows XP , 4Gb Ram and 80 Gb HardDisk).
It never comes out of the function CommPortIdentifier.getPortIdentifiers() in the RxTx library.

Stable Library
===================
Native lib Version = RXTX-2.1-7
Java lib Version = RXTX-2.1-7

What may be the problem?
