How to get a pop-up in foreground (when LibMgr refreshes)

 Hello,

 I'm adding some menus in the library manager to get an SVN plug-in (based on some scripts from Poojan Wagh) and everything's going fine apart for the display of the pop-up forms. They appear where the mouse is clicked but always behind the Library Manager... quite unpractical!

 I've made some trials and it seems the form pops-up in foreground but LibMgr refreshes right after.

So in the cdsLibMgr.il, adding the menu looks like this 

lmgrCreateMenuItem("Menu_svnStLib" "simple"
  '(("label" "SVN Status")
    ("callback" ("svnStLib" "updateIf"))
;    ("callback" ("svnStLib" "noOpts" ))
  )
)
lmgrAddMenuItems("designCascade" "L" '("Menu_svnStLib"))

and in the procedure itself (buttons defined in the 1st "..."):

    procedure(svnStLib(reason Lib Cell View file cat)

...

svnStLibForm = hiCreateAppForm(
   ?name `svnStLibForm
   ?fields list(newLibField newStTypeButton newAdexlButton newbrowser)
   ?formTitle "Status Library"
   ?callback "svnStLibFormCB( svnStLibForm )"
   ?dontBlock t
      )

...

hiDisplayForm( svnStLibForm '(-1 -1) )
;    svnStLibForm->refresh
) ; end of procedure

Now, I've tried with and without the refresh; with it, I get directly my form behind the LibMgr and without I get a pop-up for a refresh and when clicking ok, then my form appears in foreground... thus I think that the refresh (which has to happen at the end of the procedure) may be the cause for this...

I've also tried to put "noOpts" instead of "updateIf" in the createMenuItem of the cdsLibMgr.il; then I don't need any refresh in the procedure anymore, but my form still appears in the background instead of the foreground.
Last point, when copying several times (3x) the line with hiDisplayForm(), I get the form still in background but with focus (i.e. I can change the fields directly from keyboard eventhough I don't see the whole form).

I admit I'm a bit lost about this Display behavior. Is anybody familiar with this?

 Thanks in advance,
Matthieu
