I don't know which version of CLRMame was first affected by this, since I haven't fiddled with Mame since CLRMame 3.021, but now it appears that the Scanner does not like to be placed where I've always used in, in very top-left-most corner.

If I put the scanner anywhere else on the screen, close it down, and re-open it, then it'll have the scanner right where I left it. But if I position it at the exact top-left (pixel 0,0), close it down, and re-open it, the window will start up centered. :(
