Hi Raghavendra,

If you run xprop on the dialog windows you find a property like:
WM_TRANSIENT_FOR(WINDOW): window id # 0x7c00006

If that's the case, you can use the transience' defined in
XMonad.Hooks.ManageHelpers, putting it as the left-most managehook
(that is,         manageHook = composeAll [ transience' , className =?
"a" --> doShift "b", ... ] )
