I'm running asynchronous command prompt commands in cmd on Windows 7 64-bit and for some reason it affects my ability to recall previous commands just after I run them; for example:

I might run something like:

start /B rmdir /Q /S .\some_massive_directory

And next I try to press the up arrow to recall the text of the previous command..but nothing happens...is this because whatever data structure is holding my commands is locked by the process I sent to the background, or is it because I am using a network mapped drive to run my command on?

Works as expected here using some basic testing. When in that state, what happens when you hit "Down" once? –  Ƭᴇcʜιᴇ007 Nov 5 '13 at 21:04
Nothing, that's the problem...well this is an old system which has been through quite a few system administrators and motherboards...maybe that's the issue. –  leeand00 Nov 5 '13 at 21:06
Why are you using start /B? (This is not sent to the background) This uses the current window so execution will wait until executed. So you would not need the start /B. And how many cmd.exe have you open. In the settings you probably have 4 buffers for DOSKEY. When you do a start (and it is the fifth) maybe you'll loose the buffer of the last/first cmd. –  Rik Nov 5 '13 at 21:12
And you can use doskey /history to see the history. So you can check if it's really empty. –  Rik Nov 5 '13 at 21:15
