I am using Version: 9.0.0-rc3-73-ge021cf4575, release build Windows 11. Recently every time I start the schematic editor a bunch of panels open up so I have to close each of them. I do not want this but I cannot find the preference setting to stop this from happening (a “settings search” function would be useful). Weirdly, it resets all the panels as open even when I close and reopen the schematic editor.
kicad version 9 rc3 works as always regarding the panel display on my system (Win10). The panel status (displayed/not displayed) is saved and restored between closing/opening the schematic editor.
As this is currently not a stable version, but only a release candidate maybe you should try to update to the latest (todays) nightly version.
Note also that "a bunch of panels open up " is not the best description to reproduce a bug. Which panels exactly?
Normally kicad should save the actual state and reopen the schematic editor with the last used settings (panels on/off). The settings file for the schematic editor is stored in eeschema.json, directory: “C:\Users\username\AppData\Roaming” + kicad\ (= %appdata%\kicad) (see Where are the configuration files (settings, library tables)?).
If the restoring of the settings does not correctly happen then that’s a bug. But prior to opening a gitlab issue you should check all things on your side:
please update to the most recent nightly version (as said the restoring of all panels works correctly on my system, so I can’t reproduce the issue)
Do you have installed kicad with the same user account which is now used for using kicad?
you may look at the settings file eeschema.json and check:
if you close kicad: is the file updated?
there should be lines like "show_properties": true, "show_schematic_hierarchy": false,
Do these lines reflect the last used panel state (displayed true/false)?
Do you have installed kicad on the standard path? Or do you work with some network/cloud system, so kicad can’t acces the settings path?
Today I have seen the described behaviour also. It happened in the middle of the work and did not go away. On every schematic opening the following panels are opened (regardless of state on last kicad session):
net navigator
properties panel with selection filter
design blocks panel
search panel
Installing first a little older version and subsequently again the “faulty” version cured the problem. So there is a bug somewhere, but I have no reproduction steps currently.
