If you are using get image to capture the text for your sprite, be sure to set the texture flag. Like this:
sync on : sync rate 0 :
color backdrop rgb(0,0,128) : hide mouse
set text font "arial" : set text size 12 : set text transparent
t$="Hello World!"
create bitmap 1,text width(t$),text height(t$)
text 0,0,t$
get image 1,0,0,text width(t$),text height(t$),1: `<-texture flag set to one
delete bitmap 1
set current bitmap 0
sprite 1,screen width()/2-text width(t$)/2,screen height()/2-text height(t$)/2,1
while mouseclick()=0
if (timer() mod 1000)<500
hide sprite 1
else
show sprite 1
endif
sync
endwhile
end
Whatever...
