perhaps they ran out of original os39 cd's and resorted to cd-r's temporarily??? i dunno...
I don't think there is any temporarily about it.
The silvers are gone and they won't make a new batch anymore. Why should they?
It doesn't sell in quantities and it's a dead end product. Just be glad they offer the CD-R option.
There are plenty of other companies that don't offer that option either. Then such a product is really dead.
I think there ought to be a law about that! At the moment you don't offer a product for sale anymore, you have abandoned it. At that point an intermediate period of say 5 years goes into effect after which the software becomes freely distributable!
I think it's a crime when a company doesn't offer a piece of software anymore but starts yapping about the fact it's commercial software and you may not freely distribute it.
Sell it or make it freeware but don't take the middle road.
