Hi all,
In debugging my second display monitor issue I'm trying to make a little
test utility from the Racket source.
I've copied a snippet (pasted below) from
<somepath>\collects\mred\private\wx\win32\frame.rkt into a new file in the
same directory as frame.rkt.
Although it will compile (with raco make) and execute from the command line
(using racket), DrRacket refuses to compile or execute, failing with the
error message:
"cannot instantiate `racket/gui/base' a second time in the same process"
I've tried changing the order of the files in the require with no success.
Can anyone tell me if I'm doing something wrong or if I have a problem with
my configuration?
Cheers,
Kieron.
