I just had another instance of having two Alibre's running at the same time. A week or so ago both Alibre's had the same part file open. I worked on the part, saved the part, and closed Alibre. The second Alibre was still open with the same part file. I closed Alibre #2 and the part did not ask to be saved so I didn't lose any of the work I had performed on the part by Alibre #1.
Today I had the double Alibre again and dug into it a bit more. I was able to get three instances of Alibre running at once, see screenshot. I did this by rapidly clicking the mouse button 3 or 4 times on the Alibre icon on my startup bar.
So whatever mechanism, Windows system semaphore or other, Alibre is using to control the number of active Alibre instances needs some work. There is a race condition that needs to be addressed. Normally only one Alibre instance is launched, but rapid button presses trigger this condition. This was probably the reason had the one part open by two Alibre's. BTW... I am running Windows with all of its current patches (as of 8/01/21).
