I've tried both BrowserCap & uplevel with no differences.
I've cut & paste the aspx & code behind file
I appreciate all the time you've spent on this, but perhaps we both spent too much time on this!

In Mozilla, if you want an input text field as readonly you might have better luck with the readonly attribute (ie. readonly="readonly"); assuming XHMTL 1.0; but 4.01 quirks mode is probably the same.
The second bit of HTML is broken; why don't you post the Grid template. Also, make sure you install the browserCaps update -- this is important since ASP.NET will probably revert to the 3.2 HTML writer for 1.(6|7). If you don't want to do a browserCaps; then look at setting your clientTarget to uplevel.

An update to my first reply:
I've just installed Mozilla 1.7b - and no difference in enabled = false working
When enabled = false does work, the disabled attribue is IN the <input definition:
<input name="TextBox7" type="text" value="Run Time Disabled" id="TextBox7" disabled="disabled" /><INPUT type=submit value=Submit>
When enabled = false does NOT work (e.g. my textbox embedded in a DataGrid, i.e. the textbox is in an HTML table),
the disabled attribute is in never-never land as part of the <td, not part of the <input:
<tr>
<td disabled="disabled">
<input name="DataGrid1:_ctl5:TextBox1" type="text" value="the" id="DataGrid1__ctl5_TextBox1" />
</td>
</tr>
First, what versions of Netscape are you working with? For anything around 4.x or even 6.x you have my sympathy.
For modern Gecko Netscapes (and Mozilla) we have pretty good results. All of our developers use Mozilla 1.7 for development and we backport to IE. We write to XHTML 1.0 transitional (and set a doctype for that); sometimes we use HTML 4.0. To do this you need an up to date browserCap (see
http://www.asp.net/Forums/ShowPost.aspx?tabindex=1&PostID=89874).
I don't often use the built in ASP.NET validation scheme (Whidbey is a much better design); but you are right, ASP.NET doesn't include client side validation for non-IE browsers. There is at least on add on product to do this (see
http://www.peterblum.com/VAM/Home.aspx)
I don't have any problems with readonly for a textbox in Mozilla; what does the generated HTML look like?

I have stumbled across various Netscape issues, none of which appear to be
solvable by tweaking the clientTarget or targetSchema properties. At this
point, I'm not even interested in "solving" these problems - I'm more
interested in isolating them, .i.e. finding a "complete" list of issues.
Here's my list of serious issues found so far. By serious, I mean
functionality that fails, as opposed to much less serious (albeit annoying)
display appearance issues.
1) Run time changing of the enabled (or readOnly) property does NOT work in
Netscape under some circumstances - e.g. using a templated textbox in a
DataGrid
2) Validators don't work under any circumstances.
Someone correct me if I'm wrong, but this strikes me as a classic "brick
wall" problem - asp.net will get you very easily to 90% browser
independence, but when you need the last 10% you hit the brick wall, i.e.
there is no way to tweak asp.net to get you the least 10% - you have to
abandon it significantly - by writing your own complex JavaScript, or maybe
even abandon it completely - and go to Java.
