I think Marcia is on the right track with doevents,
but I'ld also attack it from the other side:

something like

local lcMyTemp
lcMytemp = this.value
strtofile(m.lcMytemp + furtherChecksYouLike(), "myProt.txt", .t.)
wait wind m.lcMyTemp + " in current seek" nowait
if seek(m.lcMytemp, ....)
   wait clear
else
   wait clear
endif

and not running under debugger...
