Campaigns - editing object text

When I double-click the text under a campaign item it is highlighted as selected but then it is nearly impossible to actually click into it to edit it. I end up re-typing the whole text as it is quicker. Using Chrome.

Hi Nick. Is this what you were trying to do?

I created a sequence called Followup Sequence, and wanted to add ‘and nurture’ to it. I gave this a try a few times in chrome, and only ran into some frustration when I was using my trackpad mouse on my laptop. with a standalone mouse, it worked quite well in Chrome.

Makes no difference which pointing device I use - seems random.
