Question about milliseconds

lets say there are two computers. One really really fast and one very very slow.

they both load up the same .swf file. If if they have preloaders would the slow computer run the .swf slower than the fast computer?

I have this button and it will not perform an action until 200milliseconds later. This is very important for an effect. would this mean that on a fast computer the action will be performed too quicky and on a slow computer too slowly?

it depends on their connections. Preloaders load based on internet connection speed, not processor performance. That will mainly just effect quality or speed of playback - but even then, milliseconds are the same to each computer.

so it wont matter on different computers. 200 milliseconds will have the same effect on both.
