Exiting viewport loop

When in the expanded perspective-viewport I am getting stuck in a loop trying to get back to 4-view. I will exit prespective into 4 view but a few seconds later loop back to perspective. A save and restart fixes the issue. Just looking for an adjustment or fix.

Hello - so running the 4View command is temporary, so to speak, is that correct? Can you repeat this?

Yes the 4-view command from an expanded perspective work space. I made note last occurrence. I cannot repeat it.

4-view command line typed or GUI double clicked will loop back to single perspective view when cursor moves into to main work space windows. What did work was double clicking perspective from expanded perspective view (got me to 4-view). At the time I was attempting to change view to lock a rotation point.
