New non-responsive update

It is very sad but after having a responsiveness for a couple of weeks (1.6.3) the new version 1.6.4. lacks responsiveness again (as did 1.6.2). As I am no programmer I unfortunately have to rely on proper programming. A key feature of any photo gallery is mobile optimization and responsiveness.
I tried a lot of gallery plugins and finally chose Photo Gallery because of its great features. Although I am still using the free version I wanted to skip to pro soon but under this circumstances I have to look for another gallery because it is unpredictable to have proper responsiveness. Very sad! Especially because I am using a lot of galleries showing a couple of hundreds of photos.
