Selection Tool temporary toggle on and off while using pen tool

Do Adobe programmers monitor this forum? This is a new problem with Illustrator CC 2017 and appears to be a legitimate program error.

In the past, while using the pen tool I could "temporarily" get the selection tool or direct selection tool "Command>Option>Tab". I could toggle back and forth but always have the pen tool under it all as the main active tool.  This would allow me to never change my left hand position and was very efficient.  This still works with the RECTANGLE TOOL but is not nearly as necessary for that. But now on the PEN TOOL, which I use 95% of the time, you can't get to the BLACK ARROW.  The step missing is getting to the "SELECTION TOOL" by hitting the "Command>Option>Tab". This makes quickly selecting a grouped object difficult. To  hit "V" to get to the "SELECTION TOOL" takes me out of the PEN TOOL which I then have to reselect. This is 1000's of extra clicks over a day or 2 due to the complexity of my illustrations.

This has to be a code glitch because it worked for years as indicated above.  It should be an easy fix if ADOBE is paying attention. Nothing else happens when I "Command>Option>Tab" with the PEN TOOL so it has not been reassigned. It just doesn't work anymore.
