I have used the datawindow back in the old days of power++ and than used it with datawindow.net. I am now evaluating powerbuilder .net to see if it will meet my requirements for an upcoming project.
I have a database table that has almost 200 fields. When I bring these into the datawindow painter it is have severe problems on displaying correctly or being able to move items around. Also the saves take about a minute to occur. This same datawindow in datawindow.net did not have this issue at all.
My fear is I will have other datawindows that will have up to 500 fields on them. With this speed this would make the project near impossible to complete.
My computer is quad core I7 with 32gb memory using all SSD's thus I am pretty sure this is not an issue with not enough power in the computer.
