Has it ever worked?  The symptoms you describe are those of EMS 3.2
hardware running an EMS 4.0 driver.  Strange as that sounds, a lot of
manufacturers have done this including Intel (I bought a dozen of their EMS
4.0 AboveBoards before learning this dismal truth).  EMS 3.2 uses a 64k
pageframe in high memory to map in 64k of expanded memory at a time.  EMS
4.0 can have much larger page frames in conventional memory, allowing the
kind of context switching that DESQview does.  You have to have the 4.0
hardware for this.
