Annoyingly I learned of this error today and have already fixed it but that
was after the release went out. I'm not sure about the other one you mention
but it sounds familiar.

Congratulations to PLT on another great Racket release.

Hello,
the Racket Portable package, for those who want to carry a Win32 Racket
installation on removable media, has been updated to the new version:
https://bitbucket.org/chust/racket-portab
A related problem that is easy to replicate (I have not reported it
through the submit bug report yet, because I would like to know if
this is some quirk of my installation):
Open DrScheme.
Type Ctrl-= to open a new tab.
Click on first tab.
This causes the following error on my system:
send: tar
Whenever I try to open a file in the new version of Racket (on
Windows), I get the following error. Anyone else having this problem,
or could this be related to the other virus-checking problems I had
with the install?

My fault.
I'd copied the Racket v5.1.2 directory off of the .dmg using 'cp -R'
Sometimes that error is because your compiled files are out of date with
your source files. Typically this only happens when you modify the files
tho. If that really is the problem, running "raco setup" from the command
line should fix the problem (once it completes).

If I remember correctly, there was some time ago discussion about a clear
default language missing from Racket. I agree. Once I started with PLT
Scheme many years ago, I picked the version that suited best at that time.
And have been using that ever since mostly for compatibility reasons. Now, I

I couldn't find a link to that URL.
Maybe it could be linked from the Community page or somewhere else?

Well, I thought I'd done what Don suggested and unfortunately now the
deadline for feedback has passed, making it difficult to change things
(impossible for the current release of course). So I think the best

Just getting ready for the new year, and looking closely at the

I like that there is now a version of overlay that works as an offset
from the middle-middle point, but it doesn't address Don's second
observation that the semantics of overlay/offset feel backwards.

Check syntax is always running, so you don't need to press the button

Hi all,
I would just like to inform you that you can now make a read-only connection

tested this with Windows XP and Ubuntu 10.04 with R 5.1 so far, but
hopefully it works with many other systems, as well. I'd appreciate an
