SplashTime, LaunchAppAfterSplash, and CloseEXE ignored when opening multiple files
A while ago, I filed a bug report for SumatraPDF (https://portableapps.com/node/65018). When I open multiple files, by marking them in Windows Explorer and pressing the Return key, SumatraPDF will overwrite its settings with a default version.
I experimented with \SumatraPDFPortable\App\AppInfo\Launcher\SumatraPDFPortable.ini and added the following parameters to [Launch]:
SplashTime=2000
LaunchAppAfterSplash=true
CloseEXE=%PAL:PortableAppsDir%\SumatraPDFPortable.exe
