# 4888 Inadvertent OutputDebugString Call Left in DBISAM Source Code

---

After installing latest 4.50 build 3 I have thousands messages like this:

Debug Output: Next: 10 Process Sender.exe (14792)
Debug Output: Next: 65476 Process Sender.exe (14792)
Debug Output: Next: 65477 Process Sender.exe (14792)
Debug Output: Next: 55 Process Sender.exe (14792)
Debug Output: Next: 64 Process Sender.exe (14792)
Debug Output: Next: 10 Process Sender.exe (14792)
Debug Output: Next: 2 Process Sender.exe (14792)
…

Then reading large blob fields. It's slow down or hang IDE.

Its comes from:
procedure TDBISAMCursor.ReadBlob(BlobBuffer: TDBISAMBlobBuffer; var RetryBlob: Boolean);

Line: OutputDebugString(pChar('Next: '+IntToStr(CurrentBlock.NextNumber)));
