Yes, I can use other commands and the first "dir" still triggers the interrupt - I can even use commands like "dir *.*" and other elaborate dir commands, but the first plain "dir" still fails. Right now, I'm using 3.01. This interrupt weirdness happened on 3.0 also - in fact, a letter on the subject to JP Software was what brought me 3.01. Anyway, for better or worse, I've sort of gotten used to it, and nothing else of the kind seems to happen. More 4DOS lore: An acquaintance of mine wrote a shell program for PKZIP and PKUNZIP, which didn't behave properly under 4DOS. As I recall, something went wrong with filename construction, like adding an extra period, so that when the ZIP shell summoned ZIP, ZIP was unable to find files. My friend patched the program (which had worked perfectly under COMMAND, by the way). I wonder, though, if the old version would work under 4DOS 3.01 - I didn't study all the changes in detail, but I think they've changed some things which might be related (I was running it under 3.0).
