>Description:
This happens on a vanila 4.3-RELEASE system.
/usr/bin/mail is used to view
a message that is longer then one screen and the pager (more) is used
If you suspend mail (via Ctrl-Z) in the middle of the paged message,
when you bring it to the foreground (fg) - the screen does not
get  restored, and  the program does not accept any commands.
The only way to bring mail back, is to repeat Ctrl-Z and fg. 
I haven't seen this behavior before (4.0 and prior).
Is this somehow related to the new "more"  ?
	
>How-To-Repeat:
Use mail(1) to read a message that is longer than the screen length,
so the pager is used. Suspend the programs with Ctrl-Z.
Try "fg" to restore it.

	
>Fix:
None available.
Workaround:
Ctrl-Z again and fg again restores the program.
