Ross, I did what you recommended - downloaded your plugin 'fix' for the disappearing arrows (ajax), saved it as you suggested, but it doesn't show up in my plugin list!
I'd been in the hospital the better part of December, part of January and part of February, so had been away from the computer for quite a while. When I got home and back on, I found that wordpress on both the sites was broken - I couldn't get widgets to move around, etc., so using my site as a guinea pig (www.ginasweb.com), I reinstalled wp, and that solved THAT problem, but...I now cannot get ajax - even with your fix - to work. I have a page called events. Pardon the site, but it's rather bare right now, 'cause I'm trying to concentrate on getting this calendar working - I maintain a site - http://www.squaredancepro.com and we need the calendar to let all the squaredancers know when/where the next dance is! Could you take a look at ginasweb.com/events and of course, the main page with the calendar in the upper right hand column - and see if you can figure out what's wrong? You won't need to register to get on - I think...I'll make sure you won't :)
Thanking you in advance for your help.
