I'm not sure we are talking about the same thing.
on table dbo.Transaction_Main_VPS, column TransferReasonCode:
'Reason for transfer (lookup). Current reasons: TPLD PledgedAccountTransfer, TRAC TransferBetweenSpouses, TRAF Demerger. TRAG Gift, TRAI Heritage, TRAN BetweenOwnAccounts, TRAO OrdinaryTransfer, TRAT Trade, TRAU UndividedPossession, TRPE TransferBetweenDifferentBeneficiaries, TTDT TDTFrameworkTransfer.'
(no tick marks)
If I put focus on the field to edit it, it and all other text boxes suddenly reformat nicely into the window size. (3 rows for TransferReasonCode)
If I put focus on a different column description, ALL the text boxes, including the text box TransferReasonCode text box, suddenly extend far off the right side of the window, requiring scrolling. (2 rows for TransferReasonCode text box).
This may be a bit more clear than setting focus (clicking) on a different table. This action occurs just clicking on another text box for the same table.
