[Text frame links and text size]

Hello! I have also been having problems with this issue. It makes Publisher unpredictable, since I never know what text frame I may have accidentally resized.
When I have a bunch of linked textframes, it is not uncommon that the text varies sligthly in size without me noticing it. 
Or, if I notice it and adjust the text size in the second text frame, and then the text flows back into the modified text frame -- the size will change again!
The only solution I have found is to delete all textframes and start from the beginning. 
Does anyone know if I can reset the size in the textframes? Or at least identify if any textframe in my document affiects the text size? Thanks!
