Yes, we had never changed delivered Cache' code until we changed
2010.2.1 to generate the html5 doctype, instead of html4, with HTMLDTD
=3D 1 and while we were at it, we put in this into the abstractPage
    If (+..#HTMLDTD) {
        &html<<meta charset=3D"utf-8" />>
        &html<<meta content=3D"IE=3Dedge,chrome=3D1" http-equiv=3D"X-UA-Com=
patible" />>
    }

so hopefully in 2012.1 the generated zen pages will put these right up
top or permit us to specify this. It took our little team of
sweat-equity partners with day jobs who are working very few hours per
week more than a year to get 2010.2.1 to the point where we are now
working on getting out of quirks mode before our next alpha tests.
That's when we hit a show-stopper delivered to everyone in 2010.2.1
but apparently something that only affects us(?). It is this:

All pages that have HTMLDTD =3D 1 (pages that are out of quirks mode)
have the location for modal group pop-ups calculated wrong when the
user scrolls down before clicking something like a calendar pop-up or
combobox or so. If anyone has a work-around/fix for this bug, then we
might have a chance of going live out of quirks mode with 2010.2.1
instead of spending 2012 mired in upgrades again rather than working
on the app. Thanks in advance for any and all suggestions.  --dawn
