A performance improvement has been made to the OSx software to give
better redraw performance when a command form is dismissed or another
area on the graphic is selected. However, a side-effect of this improvement is
that the graphic area around the "boundary box" may require an operator
command to refresh the symbols to restore their full appearance.
A magenta box is drawn around a graphic symbol whenever a command
form is used for data entry. When the command form is dismissed the
magenta box is removed and the original graphic area it covered is redrawn.
However, prior versions of OSx redrew the entire graphic. While a complete
redraw insured that the area was redrawn correctly for all possible cases, it
had a very high impact on performance, particularly when done on an
X terminal.
Now that OSx redraws only the region covered by the magenta box, there
are cases when the symbol is not perfectly redrawn (such as when layers
hold overlapping symbols or depending upon how the symbol has been
grouped). To redraw the entire screen, choose one of the following methods:
• Press .
ALT r
• Select from the root menu. (The root menu is displayed with a
Refresh
left-button mouse click on the root window. The root window is
accessible from the bottom right gray region on the OSx screen.)
• Click the cursor in the graphic, and press
quicker because it redraws only the customer graphic. The other OSx
screen areas are unaffected.
