Hi Frank,
I have tested for this issue using version 5.1.0.51 and was not able to see the problem. This is how I went about testing this issue :
1. Run the attached sample.
2. The cursor is at line 3 and column 1.
3. Press Ctrl+Space.
4. Context Choice is displayed.
5. Select ' Find ' from the Context Choice.
6. Press Enter.
7. The new text does not overwrite the existing text 'Database'.
Please let me know if I am missing something.
Thanks for your patience.
Regards,
Ebenezer.P
