keypress or minimum duration whichever comes first for moving on to next stimulus

Hello Everybody,
I am new to opensesame.
I have an issue I hope someone might help me resolve : I display a visual stimulus(about 20) after a fixation cross using sketchpad item.
i wish to display each stimulus for 1000ms
and get a yes or no response for each stimulus by keyboard or mouse
so i am having difficulty in : i want the next stimulus/fixation cross to start at the end of 1000ms or at the press of response ..whichever comes first

right now i have the settings as:
fixation cross
set duration 495
set description "Displays fixation cross"
draw textline center=1 color=black font_bold=no font_family=mono font_italic=no font_size=60 html=yes show_if=always text="+" x=0 y=0 z_index=0

for stimulus:

set duration 0
set description "Displays stimuli"
draw image center=1 file="[full_image].jpg" scale=1 show_if=always x=0 y=0 z_index=0

for mouse

set timeout 995
set show_cursor no
set flush yes
set duration mouseclick
set description "Collects mouse responses"

thank you !

Hi,

The set-up you described here should work. What exactly is your problem?

Cheers

Thank You Josh for your reply.
The problem is as the stimulus/image is presented for 1000 ms , it doesn't move on to next cue/stimulus if i press the response say at 500 ms . the image stays there till 1000ms are complete.
i need that the the stimulus should move on to next if the response is pressed OR 1000ms are over...whichever comes first.
Thank You
Chinmay
