Hi Chip -
Thanks for the awesomely quick response on this... and here's what I experienced when I updated the plugin and tried to create a new map on a post where it has been unsuccessful so far:
In html view, the "create new map" dialog on the right side of the post editing window did nothing - it appeared clickable but nothing happened. I switched to Visual, and used the toolbar button, and got the expected map with options to edit and customize. I added all the usual (address, custom marker, popup info, change size, right align) then hit save.
White screen. Wait. Nothing, so I hit Back, to go back to the map, and it was as if I had just opened up a new one - all my entered info was gone. :::sigh:::
Hit cancel, and surprise, surprise, the code for the map was added to the post (Visual view). I know because the new size was there in the parameters. I did a select and copy, then updated the post. The code disappeared after the update, so I switched to html, and pasted in the code, hit update, and it stayed.
Viewed the post,and the map is THERE as it should be. So, it IS working better, but I have to use the toolbar button in visual, copy the code and then save the post in html, kinda clunky. And it still white screens although it does create the map.
I am hesitant to tinker with already existing maps because I need to ADD markers to several already existing and I really don't want to have to recreate the whole map... :)
Thanks again for your quick response!!
