When accessing any tab from Setup - Correspondence (Classic loo), the whole application locks up. The exit button is dimmed, and while a screen appears to flicker briefly in the background, nothing loads. Task Manager is required to kill the processes.
Similar to the problem with Address file minimising and same solution. Edit the Workstation ini file (shared data directory) and remove the following from the startup positions:
X = .Number("Setup_Address_X")
Y = .Number("Setup_Address_Y")
w = .Number("Setup_Address_W")
h = .Number("Setup_Address_H")
