workitem disappearance

[Satya Atreya]

Hi All,
 
I have noticed that executable workitems once opened in 'Execute' mode but not really 'executed'  - would disappear from workflow inbox like 'already executed' workitems.
I have a user who wants to retain the 'executable' workitem in his inbox after he opens it in 'execute' mode, but backs out (using green back arrow on the top) without really executing it.
 
I would greatly appreciate any ideas / work arounds / config changes for workflow inbox views..etc.
 
Thanks,
Satya
