[Zope-Annce] ZStyleSheet bug fixed - Version 4.2.2 released

[Adrian Hungate]

I have fixed a bug with ZStyleSheet that was allowing the setting of the
"useBrowserVersions" attribute to get out of sync with the browser lists
selected for individual stylesheet objects. I also had that attribute on the
ZSSAttributes object inspite of the fact that there was little point at that
level.

I have removed the pointless (IMHO) attribute from ZSSA and added a catch
with resets the browser lists across the entire stylesheet if you switch
browser versions on or off.

You can get the updated version from
