Express Scan causes system to hang.

[wwiv]

Executing Express Scan from Main Menu (Z), with Pause enabled for user, More [Y/n/c] prompt appears on first screen, then subsequent screen is blank. More [Y/n/c] prompt still visible, but appears to hang. No longer responds to any keypresses.

Executing Express Scan without Pause enabled for user will cause a blank screen to be displayed, with no more response from system.

Backtrace from gdb below:
