Dear Matthew,
Sorry for the long delay. I will try to help you as much as I can.

I tried to install the new Racket nightly on OS X (the previous one was

Can you tell me more about your system, including the processor and OS
version?
10.6.5 on a Core 2 Duo Macbook Pro.
1. Different (horrible) antialiased font rendering when using white text
on black background. [1]
I'm not able to replicate this behavior on my machines (x86 10.6 or
PowerPC 10.4).
As a simpler test, can you run the program at the bottom of this
message in both the old and new versions and send me screen shots?
While playing with your example code I managed to narrow it down to
'partly-smoothed. It seems that it really gave full smoothing (at least
with Monaco) in the old MrEd. In the new one there is a big difference
between partial and full smoothing and with partial the output gets
worse on dark backgrounds (even for 'swiss). Strage, because I thought
that this setting was one of the things I checked before sending my e-mail.
The code:
#lang racket/gui
(define f (new frame%
[label "Text Test"]
[width 200]
[height 172]))
(new canvas%
[parent f]
[paint-callback
(lambda (c dc)
(send dc set-brush "black" 'solid)
(send dc draw-rectangle 0 0 200 75)
(send dc set-text-foreground (make-object color% "white"))
(send dc set-font (make-object font% 12 'swiss 'normal 'normal
#f 'partly-smoothed))
(send dc draw-text "send dc set-font!" 10 30)
(send dc set-text-foreground (make-object color% "black"))
(send dc draw-text "send dc set-font!" 10 105))])
(send f show #t)

With full-smoothing there are no differences (for both Monaco and 'swiss).
So I guess it's not a bug, it's a feature. ;]
2. Cmd- keyboard shortcuts do not work at all (no action).
I've had one other report of this problem, but I don't yet have a good
idea why Cmd- combinations aren't delivered as key events.
Since I'm not able to replicate the problem on my machines, maybe you
can help me debug the problem. With a few experiments.
The first experiment:
* In "collects/mred/private/wx/cocoa/window.rkt", you add a
`printf' to the start of `do-key-event'. (You won't need to
recompile anything after making the change.)
* Run the program at the end of this message.
* After the program starts, type a key; you should normally see two
printouts from `do-key-event' --- one for the key press and one for
the key release. For a Cmd- combination, you should see a printout
for the key press, but my guess is that you won't see anything when
you type a Cmd- combination.
* Be sure to remove the `printf' before trying to run DrRacket;
printing isn't really allowed at that layer of the system.
I added:
(define (do-key-event wxb event self down? wheel?)
(eprintf "~s~n" (list 'do-key-event wxb event self down? wheel?))
For normal keypresses (with Alt/Option too) I get these pairs:
(do-key-event #<weak-box> #<cpointer:id> #<cpointer:id> #t #f)
(do-key-event #<weak-box> #<cpointer:id> #<cpointer:id> #f #f)
For anything with Cmd- I do not get any prints.
It worked with both standalone gracket and drracket. OTOH The modified
DrRacket hanged hanged once during the tests so maybe you are right
about the layers. :)
In either case the output goes to original the stderr of the process (so
the Terminal or Console) and both give the same results.
A second experiment:
* In "collects/mred/private/wx/cocoa/window.rkt", change the
implementation of `performKeyEquivalent:' in `MyMenuBar'
from
(and the-apple-menu
(tell #:type _BOOL the-apple-menu performKeyEquivalent: evt))
to
(super-tell #:type _BOOL performKeyEquivalent: evt)
* Run GRacket. Does Cmd-A work? Cmd-Q?
I failed to notice that Cmd-Q and Cmd-H always worked just like Cmd-,.
Sorry.
This is fun: In 5.0.99.2 I do not have any mention of
performKeyEquivalent in window.rkt or anywhere else in collects. ;-)
I downloaded 5.0.99.3 (plt-5.0.99.3-bin-i386-osx-mac.dmg) and I cannot
find anything either.
A third experiment:
* Change the `performKeyEquivalent:' implementation to just
#t
* Run GRacket. Does Cmd-A work? Cmd-Q?
A fourth experiment:
* Change the `performKeyEquivalent:' implementation to just
#f
* Run GRacket. Does Cmd-A work? Cmd-Q?
Ditto.
3. In preferences I can only switch tabs and click OK/Cancel. Other
buttons and drop-downs do not react to clicks. I can activate and change
some of them using the keyboard (Tabs + Space).
I see this on my PowerPC 10.4 machine (though your screen shots look
like 10.5, at least), so I should be able to fix this one.
I don't know if it should but it still does not work on 5.0.99.3.
