Backup .~sql file not closing

[Joshua]

When opening a .sql file in PL/SQL Developer 9, a like named file with .~sql is created. But this file is not getting removed after I close the original file. Is this a bug, or is there a setting I need to change?

PL/SQL Developer
Version 9.0.2.1621
Windows 7 (64-bit) 6.1 Build 7601 (Service Pack 1)

Using
Home: OracleClient10g
DLL: C:\oracle\product\10.2.0\client_01\bin\oci.dll
OCI: Version 10.2
Oracle Database 10g Enterprise Edition Release 10.2.0.3.0

Thanks,

Joshua
