For what it's worth...several times I've had my SDR automatically start sending dits when I've selected CW mode, and I've always been able to make it stop by jiggling the CW Key cable that I have plugged into the back of the SDR. In my case, I've assumed that somehow the CW jack on the back of the SDR (into which the plug on my key cable is plugged) is somehow screwing up.

No amp is involved, at any rate. What usually happens in my case is that when I put it in CW mode, it will go into a "keydown" mode as if I had put a rock on my CW key (this ends up being a set of dits or dahs, then, based on the current keyer setting for speed). The cure has so far been to reseat the parallel cable a couple of times. Then, once it finally and randomly goes away, to screw down the connection to the parallel port well in hopes of preserving the good connections. I've had the problem with both USB and parallel -- slightly less often with the latter, actually. I've also had it simply assert transmit upon powering up the rig, but not as often, certainly not as often of late. There does seem to be something touchy somewhere in how the parallel cable relates to T/R switching, but since I usually get past it fairly quickly, I've never really tracked it down.
