Update broke menu display

Hi, I just updated both my WP installation, to 4.5.2, and this plugin. It was working fine before, but on update there were a couple of issues.

1. The navigation on the slider images was not correctly located. The arrows were not vertically centred; and the clickable dots were not showing unless the image overlay them. I sort of fixed this by playing around with the height, and removing the arrow navigation.

2. More importantly, the menus would not work correctly. Where a drop down menu was sufficiently large to overlay the dots, the dots, in fact, were on top of the menu, not behind it; and it was impossible to move down the menu options past the dots, so making any options lower than the dots inaccessible. The menu options just disappeared.

In the end, I’ve removed the slider images, but would much prefer to put them back, if possible. The site – without the images – is http://www.midlandgliding.club/ (using Suffusion). They were immediately below the “Go Gliding” title, and as you will see if you go to the members menu, that would have extended down below the dots under the images. It would be nice if there was a fix for this.

Thanks.
