Eyedropper tool keeps turning on after being switched out.

I have been experiencing a bug in photoshop recently. for short my Eyedropper tool is very like to re-active. when I pick a color sample, I am sure to turn my brush tool on and successfully put down a stroke with the selected color, after that first one my software is... I mean sure it will, 70% times the eyedropper active after that and I ended up going with my second stroke with the eyedropper, no second line was born and an unwilling color replaced my needed one I need to eyedrop the color I want again to continue. when working on stuff like art it started to give me depression by extending the work and breaking the flow. I hope my problem is known so I can ask for help with this issue.
