Sys Tray Icon does not turn red anymore

[Gintaras]

Do you remember some changes at that time? For example, changed system settings, installed some programs, added some macros, installed different QM version.

Try to install QM 2.3.0.13.

Try how it works with empty QM file (only with System folder and 1 macro). To create new QM file, use menu File -> New/Open File. Then restart QM.
