Goodafternoon all

I have a question. I am using version 1.4.7. I have made a template page, I have used it before without a problem, but for some reason, I now cannot select one of the textframes of this template anymore to edit text. I see the textframe only when I click on show frames, but I cannot select it and edit the text.
I am not working with layers (have not checked that out, so that cannot be the problem).
