Hi,
Not sure what type router you have but something sure sounds wrong. Have you even used the router as just a plunge router? Did it do the same thing after you locked it?
Maybe we should start with a bit more information, like the brand and model of the router, then if someone has the same router they may know what is going on.
Many plunge routers have a depth control knob which could be used to keep the depth from changing....... maybe you can try that if your is one of those models.
