Bill White at Teknowledge reports the following':'
'
System': Fugue.5'
Machine':  1108'
'
The question he asks is': "Why does TeleRaid break with Invalid Address?"  Here is the scenario':'
'
Bill was loading files, copying corresponding sources to {core}, and ended up in 9016.'
'
Hit UNDO and got Teleraid cursor'
'
Hit ^B  '
'
Instead of break, fell into 9004.'
'
Hit UNDO and got Teleraid cursor'
'
Went to another 1108, loaded Teleraid'
'
Typed (TELERAID 201Q)'
'
Got Virtual Raid and @-prompt':'
'
Typed L'
'
Displayed 1':    and then went into break': "Invalid address"'

-----'
'
[lmm': ^B inside TeleRaid is NOT guaranteed to work. It is better if you can possibly go to another machine and TeleRaid BEFORE trying the ^B. In this case, it didn''t work, and what happened is that the stack of the machine got into a bad state.]'
