Hi
At the graphic level, I am making changes to the properties of the "TabbedMDIManager" control after completing them and when I open it again all the settings are restored.
The same thing happens to me when I use "RibbonControlADV"
There is some solution to these problems, checking in forums I am not the only one
I use: Visual Studio Community 2017 Version 15.9.12
Thanks
