Run, RunWait and similar calls fail with large amounts of data

I use Run() with small amounts of STDIO data and it works fine.
Another call with an expected 750+ bytes and it fails.
Examples

  $DOS = Run(@ComSpec & " /c " & "echo ?DT | nc 192.168.1.6 80 > scan1.dta", "default","", $STDERR_CHILD + $STDOUT_CHILD)
  $DOS2 = Run(@ComSpec & " /k " & "data1.bat")
  $DOS3 = Run(@ComSpec & " /k " & "data2.bat")
  $DOS = Run(@ComSpec & " /c " & "RunDirect.exe", "", @SW_HIDE, $STDOUT_CHILD)
  _RunDos("RunDirect.exe")

Lines 2,3 & 4 are variations of line 1 in an attempt to provide a workaround.
There are yet another 10 variations all of which fail.
Note also Line 1 when run from a command prompt or windows explorer work 100% in all the variations.
Topic 188811 in forum refers if it helps.

It appears I am incorrect in indicating Run() itself is the problem.
I have discovered what causes the symptoms described above.
Immediately prior to the Run() command I have a Progress meter:

   ProgressOn("Scanning Forward", "Scan Progress ...", "Working...")
            For $i = 0 To 140
			   ProgressSet($i)
   	           Sleep(100)
			Next
              ProgressSet(100, "Complete!")
            Sleep(500)
   ProgressOff()

If I remove this Progress() the Run() command works and I collect 750+ bytes without a problem.
When I reinstate Progress()the subsequent Run() fails.

So the bug is clearly some interaction between the two calls.

The "bug" isn't clear at all, and your post in GH&S is even less clear. Please post the full script you're having problems with and not just tiny bits and pieces of it if you want to demonstrate a bug.

You have a thread running about this problem. Wait until you actually find out that there is a bug before opening a ticket - at present I would bet on a problem with your code rather than with AutoIt itself.
