SEP debug : Engine busy?

Folks:

Anyone else encounter a situation where they are about to start a SEP
debug in WDSC 7.0.0.2 and a dialog pops up indicating that the "Engine
is busy"?

No other explanation is on the dialog ... clicking OK dismisses the
dialog. It pops up one more time and then the SEP debug starts fine
(and works fine too).

The following is in my .log file after I get the error ...
