Resize block issue

Normally you can simply resize blocks but hovering over the edge of a block until the cursor changes and you simply drag it.

However, for some reason i do not have that option! I used to be able to but not now.

Can anyone please assist?

Do you want to resize Gallery block?

Which template do you use?

Can you take a screenshot block? 

Hi,

Any block really. But specifically a text and quote block in this case.

I am using Sonora.

In the pic attached i just created a text box. I am unable to change the size of the block, therefore instead of the writing going across the width of the page, it is confined to the small block area. 

Hope that makes sense. Thanks

Can you share link to page in screenshot?

Here is a little video clip. Hopefully it will make it clear

I figure it out.

It was due to 'content inset' option.

Thanks for trying to assist me
