Turns out, Lacerte remembers the scale of the window display for FORMS. On my two-monitor system, this can cause issues when the FORMS display window is scaled to the maximum view on (my) monitor 1.  Monitor 2 is horizontal, 1 is vertical, so when the forms screen is closed and called up again my Lacerte program reverts to the LAST KNOWN SCALE on the active monitor, which casues me to have to rescale the window by hand and then the auto-scale kicks in and I can see the full sheet in the display. 

I wish this wasn't so difficult to identify and troubleshoot.  There should be a setting for screen scale (default) which allows user control. 

Thanks to everyone here for helping each other when tech staff is unable!
