Why do parameters seem to disappear sometimes?

[Blacky]

You're editing a set of parameters something like this:
23689

Then you change a value that causes the display to get wider and a scroll bar gets added to the bottom of the page, like this:
23690

Then you click in the "Units" column and the table "scrolls" to reveal the units column which scrolls the "Value" column off to the left, effectively hiding it.
23691

You can click on this tool bar button to recalculate the correct widths and restore the display so you can see both columns (assuming your physical screen is large enough).
23692

Thanks (that's similar to Windows Explorer's resize to fit all columns).
