start problem
 

I have win10 home latest 1903 64bit. I have Bsplayer (latest 2.73) for several years without problems.
But for the last 2 weeks only, when I start Bsplayer with any media movie file as parameter, the Bsplayer main window starts immediately, but the video window take several seconds to open. it is annoying. other media players (vlc, Irfan,MPC…. plays the same movies immediately without any delay. the option "check for new version" and "enable taskbar" are marked off as always. I un-installed and re-install Bsplayer. I stopped the firewall. restart PC. nothing helped. any suggestions or ideas?
