Let me explain why I think so: 1) STEP 1 I donwloaded the latest ChessX code (it was 2nd of September 2025 that upon a time) and used Qt,.15.2(MinGW.8.1.0) to qmake and then make Let me point out I was always using this one on my Windows and it was always compiling well.

Which Qt version do you use - there are quite a lot og buggy versions so I still compile ChessX with Qt5.15.2 which is the only stable version I could identify for Windows. I am using 6.9.1 for Mac OS which is fine.

They only work via the Opening Tree. So you open a CTG like a database and then you select the CTG in the combo box of the opening tree (! - this is what you probably missed - by default, the combobox is on "database" and applies to your current database which has a board representation, but a CTG doesn't have one) .
