Side Panels disappear

In Bridge 12.0.1.246, the side panels in my workspace are hidden whenever I minimize Bridge or go over to any other program and then return to Bridge.  This has been a problem for a long time, not just in the current version.  I can click and slide the edges and get the panels back, but it's quite a nuisance.  I am on Windows 11, but the problem existed in Windows 10 as well.
