  That's a shame :/ Looks like I commented on that thread way back then. And I think my comment there was at least mostly correct. I was always under the impression that much of the core of the product, the interesting bits, was done in assembly, or a layer on top of assembly (they used something called SYMPL in the DESQ and DESQview eras, but I'm not sure about DESQview/X). This would have been for performance and memory constraints. I'll have to call and get clarification on all that. I might be mistaken. In the later years, Quarterdeck transitioned to building DOS and Windows applications like CleanSweep. That was the era when Symantec bought them. I always got the impression that DESQview wasn't really an interest of theirs. It would be interesting to know what they would have done with the source in that era.
