I migrated an application from PB11.5 to 12.5.1 Build 4015 (classic). The application works fine with an Oracle DB. But when I try to edit the data source in a datawindow, PB crashes in PBSQL125.dll. When I try to create a new datawindow, it crashes too. The datawindow painter works good, even the preview. There is only a problem with editing the data source in graphic mode. Data source, which is displayed in syntax mode, is okay.
The operating sytem is Windows Server 2008 R2 Enterprise (SP1), I tried the DB driver O90 and O10.
Can anybody help? Maybe with a workauround to set all data souce to be displayed in syntax mode permanently.
