# 446 A Key Not Found Error is Triggered During Many Random Operations On Table Opened Exclusively

---

I think I've managed to reproduce the bug I mentioned a few days ago to do with "Key not found" errors on exclusive tables.

Run the application dbisampl.exe and
1) Set exclusive to off - unchecked (repair the tables if desired)
2) Press start
3) no problems....
4) Press stop
5) Set exclusive to on - checked
6) Press Start
7) Get Key not found exception on NAMEKEY.
8) Turn exclusive off - unchecked
9) Press Start
10) no problems....
