Left mouse button causes moueup event despite button still being pressed.
Post: #1
Hello everyone 
I am working on mouse input for a game, I am having trouble with the left mouse button, the right button works perfectly.
I am using GLUT.
Here is my mouse event handling code.
I am using integers to keep track of the mouse button states. when the mouse button is released, this is represented by a continually decreasing negative value in iMouseLeftButton and iMouseRightButton.
When the button is depressed, it is represented by a continually increasing positive value.
The right mouse button portion works perfectly, but the left mouse button not so well.
When I press the left button, the code works fine for one cycle, after that it thinks that the left button has been released, even though i am still holding it.
I have tried switching the code around, substituting GL_LEFT_BUTTON with GL_RIGHT_BUTTON, just to see if I had written it incorrectly. GL_RIGHT_BUTTON works perfectly.
Any ideas?
Thanks in advance. : )

iMouseLeftButton = 1;
}

{
if ( iMouseLeftButton > 0 )
{
iMouseLeftButton = -1;
}
}
}
