rotate,animimage and handleimage

my bmp is here http://www.geocities.com/robhydro1/
My problem is using the handleimage command and rotating my anim strip.If I set handleimage it at 0,0 or don't use it,it does fine,but if I move handleimage anywhere on the bmp,some of my rotations blink out.

here's my preload code


;*************************************
;
; rotate 90 degrees one at a time
;
;**************************************

tmp_image=LoadAnimImage("gunL.bmp",55,11,0,4)
;HandleImage tmp_image,1,0
;MidHandle tmp_image

Dim gunL(90)

For i=0 To 90
gunL(i)=CopyImage(tmp_image)
;HandleImage gunL(i),7,0
RotateImage(gunL(i),-i)
Next

And Here's how I'm rotating it

If showgunfire=1

If MilliSecs()>gunfiretimer+100
gunframe=gunframe+1
gunfiretimer=MilliSecs()
EndIf

If gunframe=4
gunframe=0
showgunfire=0
EndIf
EndIf
;HandleImage gunL(angle),0,0
DrawImage gunL(angle),x,y,gunframe



End Function


As u can see I've tryied putting the handleimage everywhere and still got the same results.

and cure for this?
Thanks,
Rob
