Why not just download the IDL 5.1 demo version from ftp://ftp.rsinc.com,
install it on the same machine, and try running you application? Or, you
can get RSI to send you the IDL 5.1 CD-ROM, which will let you run your
application without installing IDL on your system.

As far as the widgets go, it will depend on how your program was put
together. You've probably got a good chance of success if you've already
verified that the IDL 3.6 version of your application runs on several
different platforms. However, the following items would be danger signs:
(1) The application has only ever been run on one platform (even worse,
only on a single machine),
(2) The code is single spaced, with few comments, and every line starts
in column 1,
(3) The programmer who developed it is no longer around.

Just my $0.02 cents worth.

Cheers,
Liam.
