Moreover, I found that by pressing the 'X' key can toggle the blackout mode (BKT) in els police car. I haven't touch the default ELS.ini so the BKT '\' can still work.
The 'X' corresponds to code:88 in ELS and there is no 88 in ELS.ini control section, same as the 'Q' key light issue.
Why ELS's key binding starts to overlap while nothing is changed in the ELS.ini file?
Anyone has this problem too?
