Paint.NET :: Why Won't Text Tool Work

I paste a picture into Paint.net. That works fine. Resize it, fantastic works just as I want it to. Click "text", choose a colour.. no text. Just blank. So I click text again.. blank. I choose a different colour.. still blank. It's forever making me type invisible text.

So I have to close paint.net, re-open. Text is magically working again. So I decide to make the text first, THEN add the pictures. So I write the text, all goes fine. I add the pictures, all works fine. I go to move the text and pictures around to align them properly.. nothing will move! It just creates invisible squares or makes me try and write text again, so I click on the history on the right to select what I want to move, and everything suddenly vanishes and disappears!

I know this program is freeware so I've no right to complain, but it really is infuriating when people release software that doesn't even work. I may not have paid for the program but I do have to pay my ISP for the bandwidth I just wasted downloading this pile of tosh.
