Line Tool No Longer Allows for Pixels?

[Dylan15A9]

I never want to use the line tool to create a shape or a path. I constantly use it as a straight line tool for pixels only. Suddenly it seems that this is a greyed out unselectable option. 

Is there any way to use the line tool for pixel creation only? I do not want to go through paths or shape tools to eventually create pixels. I only want to use the line tool for creating pixels.

What problems do you see with the Pen tool it seems OK on Windows?

I think you already participate in the thread about the Pen Tool issue. 

Under some circumstances the Pen Tool creates disconnected points.

It look like you can not edit a path copy in the path palette. The new path button function in the path palette creates.

Yes, agree - I find the pen tool has become somewhat unpredictable - dropping or adding anchor points or bending wildly in another direction after closing path.  

Still my BIGGEST problem with Photoshop has been the removal of the blending tool shortcut - I use it all the time and it needs to come back! I wrote an action for it but it's a pain on a laptop...
