The data base name selection list box does not allow to select the required database name when there are many databases in the instance.
Assume there are many databases in the instance which is selected for data export/import using the Wilton db transfer tool (or any similar tools like backup-restore). E.g. 30+ databases. Because of the limitation of the maximum number of data base names which can be displayed within the list box for the selection of database names, facing the issue of selecting the required database from the instance which will not be displayed because there is no scroll bar to scroll down. If we try to use the navigation keys or trying to type the first letter to navigate to those database names starting with that letter, the tool is being closed.
If there is scroll bar also to select the required database name from the list of all database names in the instance, it would be helpful.
Work around for those who are facing the same issue : Rename the required database to show on top like with a prefix '1'. Then after finishing the work, rename back to the original.
