Ah how memory fades after a dozen years. I have been having a discussion with one of the original VEE team members on this subject. The consensus is that although we discussed this as an enhancement, it was never implemented.
In case anybody actually cares, the panel actions are executed even when the panel is minimized. The only performance improvement is that windows would not take the time to do a full repaint on a minimized panel.
Sorry for any confusion.

I won't disagree. However, they did have their problems. The drivers were
interpreted code and thus ran slowly compared to a true compiled driver such
as plug&play. The driver team did not have control of the driver engine
code. The proposal to provide a true panel driver compiler never got past
the cut on the new features list. The component driver path did provide
performance improvements because it bypassed all the panel repaint and
update code. In later versions of VEE, minimizing a panel would also cause
it to revert to component driver actions.
It is all moot though. The last panel driver was written in 1994. The last
panel driver maintenance was performed in 1997. The only people who
understand these drivers now work with me over at SSS. There will never be
another supported or distributed panel driver.
