ControlGetText return wrong button caption

[geth44]

Hi,

I got a strong issue with ControlGetText: after changing the caption of a (GUI) button with ControlSetText, I am unable to read back the new caption, ControlGetText always return the initial caption "Start acquisition" (set in GUI creation). I tried ControlGetData, ControlRead, _WinAPI_GetWindowText, _SendMessageA with $WM_GETTEXT ... all return the initial caption while both AutoIt Window Info and Microsoft Spy see the correct changed caption !!!???

>>>> Control <<<<
Class:    Button
Instance:    1
ClassnameNN:    Button1
Name:    
Advanced (Class):    [CLASS:Button; INSTANCE:1]
ID:    3
Text:    Stop acquisition <<< Ok this the correct caption displayed and changed with ControlSetText
Position:    0, 0
Size:    149, 29

Anyone has an explanation ?

Thanks in advance

Show your code where you changed the caption and then tried retrieving the new value.
