Workflow task / t-code issue

[Rick Sample]

I have a task that call a t-code and skips first screen. 
On the form, the user can not exit until all required fields are
entered. 

Issue:
User does not enter all fields and saves but can not exit the screen
back to the inbox. 
Can't stop the transaction, green arrow back, etc. 
The only way to exit is to kill the session. Not good! 

Any help is appreciated.
