If you are using the new Schedules Notes tool for Doors and Windows you will know that entering the data gives you 1.5 seconds between one character and the next one to type a description.
This is a setting in ArchiCAD that affects other settings like Doors and Windows, widths and heights, etc.
If you wish to have more time to type the descriptions of Notes in the Schedule Notes tool before the text updates itself, you can change the Dialog box delay settings:
There is a setting> Dialog Box Auto Rebuild Delay.
