On two master pages, everything is identical except for the margins and the correspomding text box. When I apply Master B to what had been a Master A page, the text box retains the original Master's dimensions - so I have to manually re-size the text box to fit the new margins. This is going to be really tedious for 400 pages. Is there a way the dimensions can change automatically to match the different Master? / Thanks!
That sounds very unusual.
I wonder if the file has some sort of minor corruption
If a document is not behaving well then try
Open the IDML in InDesign
Save the file as a new InDesign file with a new name
See if the issue persists.
It could be your preferences
Try resetting your preferences:
The easiest way to reset everything is to delete the InDesign preferences: as soon as InDesign starts to boot hold down Shift, Alt, Ctrl (and Apple/Cmd if working on a Macintosh). A dialog will appear asking to delete the InDesign Preferences, select 'Yes' on this dialog.

It could be more serious
Reinstalling rarely fixes everything - you can do a complete reinstall using the

I'm not sure it's a big problem, as the file behaves normally otherwise? I just want my text frames to adjust to the size of the Master applied. If I change a page from Master A to Master B, it retains the width of Master A. (only the widths are different) I read somewhere else about "Liquid Layout" - don't know if that has anything to do with it? (Liquid Layout is news to me...) Make sense?
Applying a different master/parent page and let the text reflow in the text frame works only:
This will allow to reflow the text by applying a different master/parent page. All other constellations will not work.
Thanks, but I'm not sure this applies? My text flows nicely throughout the document. It's the text box width, which changes bewteen Master A and Master B, that doesn't adjust when the other Maser is applied. It retains the text box margins of whichever Master I applied first.
For an "ordinary" rather than Primary Text Frame on a master page thias would be expected behavior. Flowing text into those frames unlinks them from the master page.
Wait! I think what I did by clicking on the text icon to make it primary did the trick! Wow. Big difference!
Thank you. I am thrilled!. 🙂
If the document is text only, no images, make sure that all text is threaded, the correct new master applied on the first page. Delete all pages except the first, the text will rerun all pages with the new master.
It's all working like a charm now. Clicking the first text box in each Master as a Primary text box did wonders. Layouts are adjusting accordingly. (Text has always flowed fine, and remains so.)
