I would like to recommend Opera 6.0 as the browser to use with OZ 3.5.2. From what I've heard, higher versions of Opera are too unstable. Mozilla related browsers are too slow. I can tell you from experience that Konqueror-embedded (which you find in the opie feed) will cause you problems by putting cache on your romdisk, and it will crash while parsing java script.
So, use a creator to rip opera from the sharp distro, then install the pkg. Make a link from /usr/share/opera to /opt/QtPalmtop/opera (this fixes a bug). Use "Libraries" settings prog (that came with oz-compat) to make opera use the alternate libs.
OZ is great, and we should all help it along, but sometimes we want STABILITY in our lives, so stick on opera as well so you can breathe again after konq gets you angry.
