Linking textboxes changes their size

[Christina29413315q3iq]

Hello, 

whenever I try to link text between two textboxes, the textbox I'm linking to completely changes it's size. 

Is there any way to avoid that?

Do you have auto-expand tunred on as a text frame property, perhaps as part of an object style? If so, try turning it off.
