I have never tried to use an iPad on this site -- or any other. I just use it to read, and when I need to do work I go to my desktop. Yeah, yeah, I'm old-fashioned. But if anybody knows, I could use the info, too!
Checked Safari again. Still no buttons showing up. I recommend downloading Dolphin browser and see if that works for you.
I didn't know you COULD use a different browser in iPad!
Apparently the Chrome browser is also available for the iPad.
If it works as well on the iPad as it does on my Microsoft PC and Android phone it would be a good choice. I've never had a problem with any postings on this site using Chrome.
I've been using computers at home and at work since the late '90s. I've built websites using everything from PageMill to Dreamweaver. I can use XHTML. I'm no rookie. But I've never had a Mac and I find iPads a little mysterious. I don't push the edges very much.
