When I switch applications FMPA to e-mail and back to FMPA the dataviewer changes monitors.
I'm using FMPA 220.127.116.112 on a Mac Book Pro (15-inch, 2016) Running Sierra 10.12.6. The computer is set up with two external monitors. An Apple Thunderbolt display an Acer monitor connected through the HDMI port on the USB3 adapter.
The issue occurs when I have the Debugger and/or the Data viewer open and positioned on the Acer monitor or the MacBook Pro built-in display and the database is on the Apple Thunderbolt display. Changing to another application causes the Debugger and Data viewer window to vanish. Switching back to the FMPA the Debugger and Data viewer re-opens on the Thunderbolt display.
If possible it would be great if FMPA would remember the location, size and position of the call stack seperator when the debugger and data viewer windows are closed. Then have them re-open in the same position the next time they are opened.
Even if they just kept this information for the active session and started over the next time FMPA opened it would be very helpful.
I tested this in FMPA 15 and it works the same way.
