O/S is WinXP service pack 3 The executable would compile into an .exe file. But when run, a console window would briefly open then close. The program did not execute. I was able to reproduce the bad behavior with the following minimal source code, and the following raco script, which appear below. I further note that the minimal program can be successfully run in DrRacket, and can be compiled and run *without* encountering the problem by adding the -l launcher flag to the raco script. Successful execution results in a browser window opening with 'hello world' appearing in the loaded document. Any guidance would be sincerely appreciated.
