Weird behavior, Menu dissappears, Picture gets magnified

Hello,

we wrote you already through the Form in our Backend. Post it here again, maybe it will help someone else…

We would like to switch to premium, and buy the plugin.

We work exclusively with pictures.

The problem we have is inconsistent use. It often happens that we have to start over again because, for example, we can not remove a particular single block – the menu in the block has simply disappeared.

One of the phenomena is that a picture drawn to the full width is wider than the following pictures. It is in the grid, but is about 10 pixels wider. In the backend you can not “push” it because the indicators are not there anymore. If we try it “blindly” anyway, the background picture is magnified with each “Mousedrag”?!?

Sometimes the layout in the frontend gets displayed differently than previously created.

Our question is: Do we need to use a specific browser (we use Chrome on the Mac)?

Do these problems also exist with the purchase version?

Thanks in advance for your help!
Martin
