hi Alan, Maybe calling the average was a bit misleading after all :
So I created a demo database with 1 form On this form I have 12 listboxes with 1 column On load of each listbox I insert 20 columns with LISTBOX INSERT COLUMN Inspecting the 4D debug log I am seeing something I did mention below : LISTBOX INSERT COLUMN becomes slower when more columns have been inserted The first call executes in 0,001 second The last call (240) executes in 0,029 second Do you think this is normal behavior, because more "objects" are on the form? Or is this maybe a performance issue? By the way, what did you mean with " I assumed that you were "appending" column instead of inserting column before existing columns " ? I suppose you mean with the same command? Do you mean you think putting the column behind the last could be faster than when putting columns in front others?
