[Rxtx] Windows 7 32-bit issues

[Emanuel]

I knew this would be asked ^^
That's the problem, it was on a customer laptop. On a freshly installed Win7
system the problem was not reproducible.
So I know, answering such a diffuse question may be impossible, maybe I
should have asked about user experience with rxtx on Windows 7 (32 bit).
(btw. using 64-bit OS caused a bunch of different problems ... out of scope
here)
