ProgeCAD 10 and 11 both seem to have problems opening multiple (say more than 10) drawing files at a time. It will always drop one of the files and not open it. Also it initially has trouble with the display until you minimise the program, restore, switch to model, then back to layout.
The issue seems to be worse when opening files containing Xref's.
