555 working backwards?

hey,
so i wired up my 555, with a trigger button, and because i only had small resistors at the time, I used one to give a really quick period.
however when i put in a brand new 800 KOhm resistor (that should have raised the period to 8 seconds) instead of lengthening the period it put a time limit on the trigger.
so now i have an output that stays high for a faction of a second and then the chip can't be re-triggered for 8 seconds. i know people don't have an encyclopedic knowledge of 555, but does anyone more experienced have any ideas why this might have happened.

thanks in advance.

CCT diagram AND a good quality picture of what you have.

Exactly what circuit are you using?
