The latest version of Flash seems to have trouble with local content - that's to say Flash files on your own hard drive. There are settings for Flash security on the Macromedia website at this address: Flash Security settings

You'll see this part of the web page:

Click on the Edit Locations dropdown and select Add location...

Click on the add Folder button and add the LightWave folder.

You will need to quit your browser and hit F1 again in LightWave to call up the help again.

Power user hint

WARNING: If you don't know what this lot means, best leave well alone.

Look for this section of the HTML in the "LightWave_Eight_Help.htm" file in the Documentation folder.

var sStart = MM_FlashDispatch(
		 "6.0",				// version of Flash used to create content
		 false,				// require latest rev. of plug-in
		 !MM_FlashUserDemurred(),	// try to install if user hasn't said "don't ask again"
		 false,				// Override the sniffer's plug-in page? No.
		 false				// Disable auto-install? No.
		 );
if (sStart == "alt") {

Once there insert a line before

if (sStart == "alt") {

That says

sStart = "alt"

To force HTML menus. It speeds use of the online help up considerably at the loss of some prettiness.
