Does it crash or just give an exception?  Using SetSTCFocus seems to be 
working for me.  Combining that with some handlers for EVT_KILL_FOCUS 
and EVT_SET_FOCUS should do the trick.

You can also specify a marker that instead of drawing a symbol in the 
margin does a line highlight.  You could then use that to highlight 
lines, once the marker has been set for a line it will stay there 
regardless of focus until you remove it.
