Text boxes disappearing

My first attempt at creating a slideshow in FM6b is not going well:
It seems to be a lot more fiddly than in v5. When I click on the box with my text in it so that I can move it, I don’t see the hand icon. If I click outside the box for any reason, it gets deleted.
Also: there still needs to be an easy way to import one’s own snippets from FM5. One snippet I have and use all the time is a ready-formatted text box, with correct background opacity.

And if I double or triple click on a text box that I have already created in order to change the text, the slideshow snaps back to an earlier slide and removes any previous edits!
