Hi Mathias,
when I do Configuration > Dark colors theme setup... > Change the custom colors (Eg Explorer Panel Filelist colors) > Dark colors for Windows Explorer styled work flow
and click Apply
then the MultiCommander.xml under C:\Users\[profile name]\AppData\Local\Packages\48089MathiasSvensson.MultiCommander_9d7x1c4ybj2dr\LocalState\Config gets corrupted.
Specifically, <toolbars> .... <cmdlinebar> ... <launchbar value="1"/>
-> the "launchbar" turns into something like "lau..." and some asian looking character. As a result, MC will not start anymore but crashes with lots repetion of the same error message that the MultiCommander.xml is corrupted.
