What do you mean by wire frame??And are you using selection or sub-selection tool since you have mentioned about vector point I doubt if it is sub-selection tool.Could you please attach a video demonstrating the issue where we see the mismatch in the preview and the output, so that we can understand the problem better and try to resolve it.
You must be using a previous version of Flash Pro which used to show this behavior.
Live preview of shapes while editing got added in Flash Pro CC (and above). You may try out the latest version of Flash Pro (CC 2014) to see how it works.
Ahh, yes. I am using Flash CS6. Thank you.
