Along the same lines as the above....
So far, only Ralph and myself have confirmed the second-instance problem . If therefore, (as I suspect), it does not apply to any single-monitor systems, then I think we could safely let the subject drop. - I can't think of any situation or time where we might want two instances of a MA3 window running at the same time. - In addition, if Jim is not running multi-monitors, then he has no hope of tracking it down...... If indeed it needs tracking down.

Also, MA3 is working as intended on my other single-monitor PCs, (ie a second-instance window is prevented from starting if another window is already running). - So unless any single-monitor user can report otherwise, then it seems reasonable to accept that this is just another quirk that will only arise where a second monitor is present.

However, - surely the intended ReadMe/User Manual should cover multiple screen use? - MA3 is after all, specifically designed to run on at least two screens. - So perhaps a description something along the lines of the following should be included....
On multi-monitor systems, any attempt to start a second-instance window of MA3 will not fail, (as intended), but is likely to cause a locked second image, requiring MA3 to be closed down in order to clear the locked image. - Additionally, it is recommended that the size and shape of any MA3 'window' must be contained within the screen area of the Primary monitor only, if normal running is to be achieved. - If any part of the window should encroach onto a second screen, then the FPS will drop dramatically. - Setting-up which monitor is to be the Primary monitor, is therefore also important.

But as stated by Morgan...

.... Otherwise, it becomes a case of, 'The-blind-leading-the-blind'. - (Or even worse, the product of a committee!)
