known bugs:

 -- mouse cursor does not appear when the working page is not the first one

 -- completly nuts in PDS when using strings (sometimes in qb45 too)

 -- num/caps/scroll lights screwed up after shutting down

... bugs only reported in my crappy box ...

 -- timer mod when in pure dos isn't restoring the PIT mode/rate as expected
    by BIOS; the DOS/BIOS time gets locked

 -- when allocating only one MEM DC, the dos box where the prog was running, 
    simply closes after the program finish, w/out reporting anything or going 
    back to prompt

 -- (...)
