Hi Rocky:
I am almost sure that you have tested this but is any value is the array set
to 'null'?
Jim

Rocky,
Shot in the dark but is this zero-based? And if so does this affect a
deletion/insert operation?

I tried the decompile per your suggestion yesterday but no change. I guess
it'll be one of those enduring mysteries of Access. :)

I'm on Access 2002 (XP), but that really should not matter. I'm still
leaning towards a corrupted module and suggest that you try the decompile
process to see if it fixes it - don't forget to back up first.
E.g.
"C:\Program Files\Microsoft Office\Office\MSACCESS.EXE" "d:\My
Documents\access\mayapp.mdb" /decompile

Here it blew with the With/End With and when I removed that and added the
mudTH(n) explicitly (mudTH(n).x) it worked. Go figure. I'm using A2K3.
Don't know if that makes a difference.

I don't think so!! :-)
This code runs without complaint...
Type fooBar
x As Long
y As String
End Type
Sub ArryTest()
Dim lngDeletes As Long
Dim mudTH() As fooBar
ReDim mudTH(1 To 41)
With mudTH(1)
.x = 1
.y = "one"
End With
Debug.Print mudTH(1).x, mudTH(1).y
lngDeletes = 40
If lngDeletes <> 0 Then
Dim lngTemp As Long
lngTemp = UBound(mudTH) - lngDeletes
ReDim Preserve mudTH(1 To lngTemp)
End If
End Sub
I still favor the corrupt module theory.

FYI:
I figured it out - brute force, binary search - ReDimming various places in
the module until I found where it failed. Turned out that if you use
With/End with on the array, it's locked - and apparently stays locked for
the duration of the module. Don't know if there's a way to unlock it. End
With doesn't do it.

Arthur:
I tried this:
For lngI = 1 To UBound(mudTH)
If mudTH(lngI).fOrdering = True Then
If lngI <> UBound(mudTH) Then ' if not the last record in
the TH array
For lngL = lngI To UBound(mudTH) - 1
mudTH(lngL) = mudTH(lngL + 1)
Next lngL
End If
lngDeletes = lngDeletes + 1
ReDim Preserve mudTH(UBound(mudTH) - 1)
End If
Next lngI
'If lngDeletes <> 0 Then ReDim Preserve mudTH(UBound(mudTH) -
lngDeletes)
Where before the first ReDim was commented out. I uncommented it and got
the lock message first time .fOrdering was True. The rest of the code moves
all the downstream elements of the array up one element to delete the
current element.
It's a legacy app and really one huge bowl of spaghetti. I'm thinking about
going around the problems by substituting a variable lngUboundmudTH for
everywhere the code uses UBound(mudTH) abd just reduce that variable in this
case by lngDeletes.
But finding all occurrences of UBound(mudTH) could be a problem since it
might be in Control Sources, Record Sources, stored queries, almost
anyplace. Like I say - legacy code.

Just a wag, Rocky, but what if you ReDimmed the array element by element? It
might be that something somewhere in the middle is causing the problem. You
could easily find out whether the whole array is locked by just shrinking it
one element. If that works then try the loop and decrement the size until
she goes boom. Just a wag, as I said.
