Thank you for your post.
I'm not sure what you mean by "roller window".
As far as field formatted as a pop-up menu not advancing to the next FIELD (not record), set up an OnObjectModify Script Trigger for the field, and have the script trigger execute a script with the following two script steps:
Commit Records/Requests 
This will commit the data, close the pop-up menu, and not advance to the next field.
Let me know if you need additional clarification.
Perfect! works great! Thanks TS
