Default Refreshing tab problem

Hi to all,

I do not know if anyone can help me on this one.
I have a form that contains a tab control with 15 tabs on it, tab 1 contains
approx 120 fields, half of them are calulated fields that are being updated
on the current event of the form thru a private sub.
On the tab control, I have 6 page with 1 subfrm on it, 2 pages with 4, 1
page with either 6,7 or 9 subfrm, very few subs are failry complex but most
of them contains less than 25 controls on them.
Loading the main form that have the tab control takes less than 1 sec. The
pages are program to be loaded on a per demand only,sample code I currently
use:

Case Me.pagProfile.PageIndex

Me.cmdHome.Visible = True
Me.Application.Echo False
Call Disconnect(intIndex)

If Len(subfrmBranchSignage.SourceObject) = 0 Then
subfrmBranchSignage.SourceObject = "subfrmBranchSignage"
subfrmBranchSignage.LinkChildFields = "IdBranch"
subfrmBranchOther.SourceObject = "subfrmBranchOther"
subfrmBranchOther.LinkChildFields = "IdBranch"
subfrmBranchAccess.SourceObject = "subfrmBranchAccess"
subfrmBranchAccess.LinkChildFields = "IdBranch"
subfrmBranchBarrier.SourceObject = "subfrmBranchBarrier"
subfrmBranchBarrier.LinkChildFields = "IdBranch"
subfrmBranchBasics.SourceObject = "subfrmBranchBasics"
subfrmBranchBasics.LinkChildFields = "IdBranch"
subfrmBranchElectrical.SourceObject = "subfrmBranchElectrical"
subfrmBranchElectrical.LinkChildFields = "IdBranch"
subfrmBranchConcept.SourceObject = "subfrmBranchConcept"
subfrmBranchConcept.LinkChildFields = "IdBranch"
Me.Application.Echo True
'reset variable for the next disconnect() call
intIndex = Me.pagProfile.PageIndex
End If

Private Sub DisconnectOptions()
'disconnect all objects in option page
If Len(frmRenewalOptions.SourceObject) 0 Then
frmRenewalOptions.SourceObject = ""
' frmRenewalOptions.LinkChildFields = "IdBranch"
frmExpansionRights.SourceObject = ""
' frmExpansionRights.LinkChildFields = "IdBranch"
frmCancellationRights.SourceObject = ""
' frmCancellationRights.LinkChildFields = "IdBranch"
frmRefusalRights.SourceObject = ""
' frmRefusalRights.LinkChildFields = "IdBranch"
End If
End Sub
the commented lines generate problems.

The main problem is when I load a new tab, the controls in them are turning
white while waiting to painted, (just imagine seeing your screen changing
line per line of pixel), this loading can take up to 3 secs.
Is there anything that can be done to improve this process, the white boxes
thing ??
My back end is on a network and just had it tested today regaring the so
call updating delay, I am currently waiting for the detailled report but from
the first look at it, it will not be the problem
My back end contains approx 150 tables broken down to respect as much as
possible normalization.
I currently use intel 3.4 Ghtz CPU, 2gig or RAM and XP Pro with Access 2007.

Many thanks
