[Rpcemu] Issues with 0.8.9 on Mac (Mountain Lion)

I have similar issues on my single screen Mac Book Air running Lion, so I wouldn't have thought it was anything to do with the dual screens.

So, I think that does support the hypothesis that the issue is some offset calculation.

Mac OS X allows you to position the logical geometry of the two screens adjacent to each other (to the left or right) with an arbitrary vertical offset of a smaller screen against a larger one.  I'll need further play-time to determine if this, or simply the dual screen setup, is a factor.

When returning to the window, the position of the RISCOS mouse will get clamped to a particular boundary and not move beyond that - perhaps affording some movement in a portion of the RISCOS desktop, but not all.

I wonder if this has to do with multiple monitors (which I have), but I haven't tried on a single monitor system yet.  This bad state seems to get reset if the RPCEmu window is deactivated and reactivated (i.e. click on another window, then click back on the RPCEmu window's title bar), but the situation will arise again once the mouse leaves the window bounds again.
