You need to share more information than this.
What exception is raised?
Preferrably you should send a sample app for me to test.
I'll give it a quick look though since I'm about to make a new sub-release.

Thanks,
Jason Wharton

Subject: [IBO] IBO 4.9.8 - TIB_Cursor bug with pessimistic lock?


Sorry for my previous dirty email...

Hi Jason,

please verify TIB_Cursor with pessimistic lock because when i call Edit()
application hang with an exception.

TIB_Cursor SemaforoC SQL: Select KEYTABLE1, USER From SEMAFORO;

Code :

SefamoroC.Prepare();
SemaforoC.First();
SemaforoC.Edit(); ç Here application does an exception

The same code work properly if i using a TIBOQuery instead of TIB_Cursor.
Best regards,
Enrico Raviglione.
