Hi Tony,
does this only happen with one specific program or can it happen with any
win32lib program?
This error indicates that a Windows handle (hWnd) which had been associated
with a given win32lib control, is now associated with a different control.
This is not supposed to happen. When win32lib creates a control, it gets
asks Windows for a hWnd for it then sets the GWL_USERDATA for that handle to
the id..
VOID = w32Func( xSetWindowLong, { hWnd, GWL_USERDATA, id } )
This stays in effect until the control is destroyed. Both the ID and the
hWnd can then be reused. But what this error seems to be saying is that two
controls are sharing the same hWnd - which I would have thought is a no-no.
Are you destroying and recreating controls in your program?

Derek.

Subject: WIN32LIB Error on Open
I think this has been asked before but anyway, why do I sometimes get the
following error when I launch an exw program.
I use win98se and win32lib 57.9 with euohoria 2.3
If required I can send the whole ex.err file.
ex.err report:
