Reply To: Disappearing Text. Help! Only three days before we go to press!

That's a behaviour of the text tool. If you click into a previously drawn rectangle (even a single click), the text tool will convert it immediately into a text frame with, as you noticed, the cursor in the top left. I find I'm having no problems at all drawing a new frame over (“inside”) a rectangle by dragging over it.

You will have less problems with this if you drag-and-draw new text frames outside all objects on your page, type in your text, then drag that frame to the required position.

(Post-edit) .. since you mention “top of the page”, this suggests you have a rectangle or text frame all over your page — possibly even on your master page. Still, creating new frames outside any existing object ought to “solve” (well, “circumvent”) this.
