I fixed this problem.
c:\Users\All Users\Team MediaPortal\MediaPortal\MediaPortal.xml - change <entry name="autohidemouse">no</entry> to "yes"
Dear Mediaportal, you support is fu**ing bad. Really.
Why there is hidden option in XML and nothing in MediaportalConfiguration.exe ?? If you remove it from configuration programm, please remove it also from xml at all or ignore.
Why 'autohidemouse' changed by himself some month ago ?
Why there is no info in KB ?
Why you ask logs and driver info where answer is so simple ??
jameson_uk, thank you.
