Isn't event.clientX and clientY supposed to return an integer value? If so,
why isn't this working? Thanks. 4  21667

How are you defining "isn't working" in this context? As this (almost)
IE only code is doing exactly what it is being asked to do in IE 6.

Well, I expect it to write the x position and y position of the pointer, at
the time of my clicking the link, to the text fields. Why is this an almost
only ie code? thanks.

You expect "event" to be a global value. That is an IE-specific
assumption, and it fails in most other browsers.
Solution: let "event" be an argument to the function.
You don't need the +"". Anything assigned to an input elements
value is automatically converted to a string.
<a href="#" onClick="getcoo rds();">Click here</a>
You forget to return false from the onclick handler, so after the
getcoords function has run, the page is reloaded (with an "#" at the
end of the address).
Change to:
<a href="" onclick="getcoo rds(event);retu rn false">Click here</a>
(also passes event as argument to function. The event is available
inside the code of HTML event-handler attributes as the variable
"event", so it is ok to write "event" here).
Isn't event.clientX and clientY supposed to return an integer value?
They are supposed to *be* integer values.
Functions return, values are.
If so, why isn't this working?
"Not working" is close to useless as an error report. When asking for
help, you get the best response if you say:
1) What you do (code, what to click, etc, so we can try to recreate
the problem).
2) What is supposed to happen (hard to guess since it doesn't)
3) What really happens for you (maybe we can't recreate the problem)
In your case, the code works perfectly. Then the page is reloaded.

And that is exactly what it does on my IE 6 (with the caveat that the X
and Y coordinates are relative to the upper left corner of the inner
border of the client area).

The function called by the event handling code uses the global
identifier "event" and originally only IE browsers supported a global
event object, more recently, in a bid for compatibility with IE, some
other browsers have implemented global event objects, but not all.

Firefox does not support the IE specific 'event' identifier and just quits

..... even though the identifier only turns up in code marked for IE only ...
Does this seem reasonable?

The problem arises whenever i try to close the window by resizing it

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
