I'm an Indesign novice, though I've successfully completed some minor personal projects. However, now I cannot create a text box in a new document. I have found I CAN create a text box on the side outside the document and then drag it into the document and then type in it. But when I put the text tool in the document nothing happens. I assume something is turned off or on when it shouldn't be, but I can't find out what. Suggestions?
It may there's a stacks of text frames on same layer, are you trying to put the text frame on it's own layer and put this layer on the top and try again.
Possibly a large frame serving as a background? Check the upper left corner for the blinking cursor.
If that's it, the easiet way to deal with it that I know is to put it on its own layer and lock the layer.
