Your "bug reports" are not really well-structured, you know? So currently you no longer have a reliable test case, which safely fails?

In this case one will have to wait until you got one again. But you can prepare at least one thing now: to make sure that you can easily switch the DOS then (FreeDOS/EDR-DOS/MS-DOS) with all other parameters unchanged (FAT partition, drivers loaded, DOS/DOSDATA loaded high, UMBPCI/EMM386, DOS Buffers).

MS-DOS forever!
