During printing, if a table header text is too long, it does not overwrite other header text any more.
Prevent closing of already closing application (double-click on form’s “X”).
Corrected warning messagebox’s caption.
When resetting to default screen layout, reset maximized and/or minimized panes as well.
Disabled Open Sec.Db.-, Save- & Save As-tools while no project is loaded.
Improved handling of non-existing tables in the secondary database.
Corrected conversion from internal value to visible texts while importing from Excel.
Corrected check for empty table while upgrading from older version.
After changing the project norm, recalculate function statuses [bug 19].
If a project model option is changed by the program during processing, that change now is shown/saved.
X-axes unit/description is no longer written through x-axes tick texts.
Corrected x-axis scaling error to avoid crossed-out x-axis.
Overflow error on x-axes due to missing y-values corrected.
Y-axes texts orientation changed to same as on screen.
With MultiGraphs, handle sec.db.-data correctly if it has empty values.
Linked y-axes in MultiGraphPrint now are printed correctly.
Erratic zoom when clicking on MultiGraph curve area removed.
Empty fields in MultiGraph setup pane were not correctly saved.
After showing a MultiGraph with data from a sec.db., reset program to primary db.
Disable water- and ground-checkbox in initial view of PipeDraw.
With pipeline drawing, disabled bend indicators and polygon points if x-axis is “AX-LP”.
Do not show the gray/white background of the pipeline drawing on paper.
Can’t jump any more if no rows in grid.
Empty locked tables don’t change status any more if viewed.
After row insert in table, active row no longer switches to last row.
Default values are now also inserted in (empty) cells which is currently edited.

Hardware key errors during Design Function processing now correctly reported.
Print page orientation and margins now correctly used.
Fixed database writing errors after importing data into a table with empty rows at the end.
