I don't think so, here's the process: 
Lanch open FMain that wait for input,
btn Ok opens a 2nd window that 1st seek a DB to recover languages, procedure names,
  schemas & user names,
I left-click on an item and choose an action in popup,
The small frame that input data for choosen action takes ~1.3sec to show @ 1st 
  (further uses are instantenous!)

A timer is runnig on the 2nd Form to drive the selection bar of popup (25ms).

Code is quite simple
without:
  blah blah process
  frm_Group.Visible = TRUE   ' Frame that contains next textbox
  txb_GroupName.SelectAll()  ' Select all default text in input zone
  
with:
  blah blah process
  frm_Group.Visible = TRUE
  txb_GroupName.SelectAll()
  txb_GroupName.SetFocus()   ' Aaarghhh

For ergonomy I must do that, otherwise the focus isn't on text at opening

I don't think so because the procedure isn't that long and that complex, so if
I setup a timer, it must be in another place than this procedure; this is the
beginning of a future whole mess.
