I don’t see how to delete this topic. I beat it up and made it work.
I have an existing Draw document in ODG format. I have tried everything I can think of to select and modify the text boxes in it. This is weird. I am in 7.4.4.
Only the owner of the question can delete it. Have you tried to click on the … icon below it? This will reveal extra tools, among which you should find a trash bin.
