We've been in the process of migrating an application developed in Delphi 5 with InfoPower 3K to Delphi 10, InfoPower 4K. At least a couple of CustomEdit controls in a TwwDBGrid control flicker and spike CPU usage at certain junctures in the migrated code, often in association with the creation of new records. The code in the Delphi 5 version of the project behaves, as always, reasonably.
The grid's CustomEdit controls where I've detected the behavior are a TwwDBLookupCombo and a TwwDBComboBox. Has anyone else encountered this sort of problem?
