"Neil Miller" <miller AT citilink DOT com> was overheard mumbling
incoherently about Mouse Drag Problem: Allegro:

>Well, thanks to the gracious help of the posters of this ng, I have a real

>I am using Allegro, trying to make a circle at the point the cursor is when

>Do you get the question? I want the user to just be able to draw one circle

I can't tell exactly what you are doing, but it sounds like you are
accessing mouse_x and mouse_y several times.  Just assign these to
different variables (i.e. "int mx=mouse_x, my=mouse_y") and use those
instead.
