Help debugging medical education applet

[Grog]

Medical Educational Applet.
Written some years ago - runs with some irritating bugs.
May be veiwed at:
http://www.acid-base.com/abdiag.ssi

My debugged code compiles and executes perfectly on the Applet runner,
but fails on several combinations of browser/platform.

Development environment:
Mac running OS 10.3.6 with current release of Xcode

Is there a kind soul willing to assist this retired medical educator?
Preferably one also blessed (cursed ?) with the same environment.
Thanks,

Grog

...hmmm. OK.

Saw no stacktraces in my console using WinXP for ..
IE 6.0026 running JRE 1.5.0
IE 6.0026 " MSVM 1.1.4
NN 4.80 " Symantec 1.1.5

That is a wide range of VM's. From the first that I
know that existed for a browser, through the current release.

It also seemed to work logically as far as I understood
it (which was 'not much') in all three cases. The upper part
of the graph showed variants of 'blue/good' and the lower section
displayed 'red/warning' with text appearing in the texarea
with scrollbars as required. Did I miss something? (Lots?)

My debugged code compiles and executes perfectly on the Applet runner,
but fails on several combinations of browser/platform.

Which ones? Please be specific about OS, browser (make
and version) and Java (make and version)

The last can be answered here..

Development environment:
Mac running OS 10.3.6 with current release of Xcode

Ughh.. I gave up on even *supporting* Macintoshes in any serious
way when it turned out that Java for the Mac needs to be specially
set-up and packaged to invoke 1.4 Java.

Is there a kind soul willing to assist this retired medical educator?

....hmmm.
How much code is there in kilobytes? The reason I ask is that well
meaning professionals[1] who write Java programs generally write
absolutely terrible and hard to read code.

I would be looking to get you to trim it down to the shortest
compileable example[2] that displays the problem. And yes, you
heard me right 'problem', singular. Solve one problem at a time.

[1] I'm guessing that roughly describes you, you were in the medical
field, but wrote this applet?

Preferably one also blessed (cursed ?) with the same environment.

[ I suspect that is asking too much. Most Java developers seem
to run Windows or Linux. ]

Nothing horrible on Mac OS 10.3.7 with Safri or Firefox. The
diagnostic text box at the bottom has justification problems. Also,
the button labels on your "Interactive Henderson Equation" don't
show up reliably. Are these what you mean?

[gratuitous remarks about Mac OS and "well meaning professionals"
elided]

Excellent advice.

Not really.

Or Mac OS.
