Hi Keith,
sorry for any inconvenience. Actually, this is an old bug which I though to be fixed. Apparently it still occurs. Which VK Player version do you use? Would you mind taking a screen shot to further explain the problem?
You can still remove the preferences file, which is an old workaround for this issue and should work.
You should find the ***_preferences.obj file somewhere near
/Users/<username>/Library/Preferences/<***VKPlayer with ID***>/Local Store/
Hope that helps,
