Because this problem occurs only with LyX and not elsewhere, I wonder whether LyX somehow misinterprets my settings.
LyX does not and also cannot change the keyboard mappings of Windows. This would requie to use a Windows API and we don't do this as we are platform independent. Maybe Qt (a library we use) does this. But I never heard from a problem like yours. So I cannot help you further.
