Hello,
Now that Microsoft has officially released the ISO for version 24H2, we are all affected by this problem. ObjectDock 3.01 disappears every time Win-D is used.
Tested on a fresh installation of the OS, with no other software installed apart from the base OS.
None of the possible settings for ObjectDock 3.01 seem to work :
The docks disappear every time we quickly return to the desktop (button in the bottom right corner of the taskbar or using the Win-D command).
