Thanks Martin & Jake for the replies. Got me thinking afresh and WALLOP! Jake, I *think* there is a solution (or two)... and I've 2 more questions... the solution requires TransMac ( http://www.asy.com ) or maybe it doesn't... (I'm probably doing this belt 'n' braces stylee)... and as I have no easy access to anything other than my own old Mac I can't yet tell if this works for all Macs, but fingers crossed here's howto:... <solution type="belt"> In CDEverywhere, under the Platform tab there are some Mac advanced options so there's 2 things to do here: 1. Selecting 'File types' > 'HTML Source' and then 'Edit' brings up a dialogue which (seemingly) allows the Type and Creator info to be edited. (For the file type HTML Source by default Type is 'HTML' but creator is blank). By some delving (using TransMac) I discovered that the creator code for NN is "MOSS" whereas the other one is "MSIE". Since my entire CD is designed to run as a web browser thang, I also edited the default type to be HTML MOSS (it was TEXT ttxt. 2. Selecting 'Misc' reveals 2 checkboxes - 'Scan file content to determine type' (which is unchecked) and 'Include Desktop Database' (which is checked). I checked the 'Scan etc.' box. </solution> That may be enough to do it, but here's an additional step by which I also managed to change the icon for the start.htm file. <solution type="braces"> 1. On the Mac, I formatted a floppy, copied start.htm to it's root, opened the file in NN and resaved it again as HTML source, and then changed its icon. 2. Using TransMac on the PC I right-clicked the file and checked its properties before copying it to my PC using BinHex (HQX) (Mac to PC copy settings under Options). 3. In CDEverywhere I then simply drag'n'dropped the HQX file to the Mac volume root.... et viola! </solution> Applying the above, my CD now autostarts, double-clicks, or drags'n'drops (to either browser) OK on my old Mac. My remaining questions are: 1. What will happen if another user hasn't got NN? Will they get the same "What do you want to open this with?" question, or does a Mac which hasn't got the creator open a file in a default application (e.g. it may use I.E. for my HTML type files, even though their 'creator' is NN)? 2. Can I somehow copy the FILEID.DAT and OpenFolderListDF_ info using the TransMac BinHex method so that the folder (also) automatically opens on the user's desktop? (TransMac indicates 2 items in the root of the floppy - 'OpenFolderListDF_' [FOLD MACS] and 'Desktop' [FNDR ERIK] )... I'm experimenting with that one now... I've made the image and am about to burn it... I'll let you know what happens.
