Can't rename, Case Sensitive

[GoogleCodeExporter]

What steps will reproduce the problem?
1. save session as "Test"
2. try to search for session (Shourtcut>Open Session). "Test" will work, "test" 
will not. Search is case sensitive
3. edit Session, rename "Test" to "test". You can't save it because it have 
same name

What is the expected output? What do you see instead?
allow to rename

What version of the product are you using? On what operating system?
1.4.0.5 (last)

Please provide any additional information below.
you can save "Test" to "Test2" and then rename it to "test".

Fix case sensitive search OR allow to non-case sensitive rename would be great.
