[BUG] Can't use Squeakland plugin very well from Firefox...

Hi all,

I just tried to use the Squeakland plugin on my Mac Mini. I'm running
the most recent version of Tiger (10.4.8), and I have a Squeakland image
that I just downloaded.

I'm using Firefox 2.0 as a browser.

When I try to run the test project from the Squeakland website (or the
Weasel Essay):

* I get a SyntaxError notification, with the text:

'Nothing more expected-><'

* Somewhere up the stack I see a "Message not understood:
ByteArray>>string". The CodeLoader's stream is a MultiByteFileStream;
its converter is a UTF8TextConverter.

* Trying to use the "mail bug report" menu choice from the debugger, I
can't use Cmd-S to do an "accept". In fact, all Cmd- keys are
intercepted by Firefox. Unfortunately, there is no text context menu in
the "mail bug report" text editor.

* Control-clicks are sent to both Squeak and Firefox, sometimes
resulting in both context menus coming up.

* Repaints are unreliable. I sometimes have to drag the Squeak objects
around to get them to repaint.

* Here's the full stack at the exception:

I'm getting the same error on a PowerPc G5 with 10.4.8 in both
Firefox 2 and Safari.

Re: [BUG] Can't use Squeakland plugin very well from Firefox...

People who want to test the latest version likely need to email me
for instructions how to uninstalll the old version and
setup the new version. This is a beta version, and I suspect there
are a number of fixes to be made before we
make it the production version. I'll note for example it will not yet
do full screen mode in the browser because I've not added that
feature yet.
