Fill-in does not get filled under Windows NT

[Jan Doggen]

Hi everyone,

we have an app that updates a screen like this (the running procedure has to find
the window, because it is dynamically generated and compiled .p code):

hCurrent = SESSION:FIRST-PROCEDURE.
DO WHILE VALID-HANDLE(hCurrent):
hNextProc = hCurrent:NEXT-SIBLING.
IF hCurrentRIVATE-DATA = 'pstart' THEN
RUN pShowStatus IN hCurrent (INPUT iRecTeller).
hCurrent = hNextProc.
END.

This works fine under Windows 9.x, but not under Windows NT.
Any ideas, anyone?

Thanks,
Jan
