Setting min/max value does not work about glvis

Thanks for reporting this. I can reproduce it on Linux, though it seems to work fine on Mac.

Revising the if statement as follows seems to fix it:

void KeyF7Pressed(GLenum state)
{
   if (state & ShiftMask)
   {
      // Shift + F7 code
   }
   else
   {
      // F7 code
   }
}

@v-dobrev -- what do you think?

Sounds good to me - make the change.

@najlkin, can you confirm that #84 works for you?

Yes, it works perfectly for me 😉 The issue was hardware specific maybe. I have tried master branch at a different computer with nearly the same OS and there were no problems at all. It seems that certain piece of hardware in combination with certain OS sets some extra stuff in the state variable, but there is no need to test all bits anyway.
