Description:
If you use the "Place a Relationship Using Existing Columns (Quick key - press 6)" option, to draw a relationship line from table A to table B, the hover over the line, the columns that are linked will highlight in orange. If you then use CTRL + Z, the line will dissapear, but the highlight will stay visible and you cannot remove the highlight - you will have to draw the line again and hover over the line again, then un-hover and then use CTRL + Z to remove the line

How to repeat:
1) make two tables
2) add some columns
3) use 6 to draw a relationshop line between the two tables
4) hover the mouse over the line, the two linked columns will highlight
5) use CTRL + Z to remove the line

the line will be gone, but the highlight will still be there.

Suggested fix:
Update the screen after a CTRL + Z removed line

Thank you for the bug report. Verified just as described also on Mac OS X 10.5.x.

Noted in 5.2.34 changelog.

Control+Z in the Model Editor did not always refresh the screen
correctly.
