So, now that the map is showing ... unfortunately the zoom in/out slider is messed up. I have the map shortcode on a page; theme uses left and right sidebar with page content appearing in the middle/majority section, the sizes of each are fixed (sidebars each 260px, center adjusts per screen width).
The Google pan control button (circle with up/down & left/right arrows) displays fine, but the vertical zoom in/out slider appears to be compressed horizontally, with the +/- buttons barely visible and shifted left of the vertical slider bar. The button on the vertical slider is also affected, and the slider bar itself is not visible at all. The person icon at the top is not seen, other than where it should be if it weren't 'squished' to only a few pixels wide. (sorry, working on a hidden sandbox version of my site that isn't public, so hopefully I've described the effect adequately; too bad can't attach screenshot here).
I haven't played around with my theme's sidebar/body dimensions yet, and would prefer not to as a solution for this ... if you've any other ideas I'd be much obliged!
