Entering text into an RTE field in a Response type window. The right margin is set to 7 1/2 inches. We have a client who opens this response window, and finds their right margin is set to 3 inches - too small for them. When they move the right margin to 7 inches, then close and reopen the same window, the right margin is automatically reset to 3 inches. We can reproduce this in-house, in reverse: when I change the right margin from 7.5 inches down to 3 inches, then exit and re-enter this window, the right margin automatically resets to 7.5 inches.

Questions:
1) how does this get automatically set?
2) how do we address this so that any right margin changes are preserved, so the next time a user opens the same window, the changes are in effect?

I thought this would be as simple as clicking the "Save And Exit" menu option, but that has no effect.

Thanks in advance!
