[Stackoverflow] [Progress OpenEdge ABL] Launching a window causes error 566 concerning buffer sysa

[Dominique]

Inside a window, I try to open another window, like this:

RUN "OtherWindow.w":U (
INPUT        E-Par1,
...
INPUT-OUTPUT E-Par4,
...
INPUT        E-Par11
).

Usually, this works fine, but now I get error 566 concerning buffer sysa.

There exists a table sysa, but I don't see the link between that table and the current error message.

In top of this, the first line of my OtherWindow.w looks as follows:

MESSAGE "first line" VIEW-AS ALERT-BOX.

I don't see that message, so my second window does not even get opened. That second window has been compiled and the corresponding *.r file is present in the same directory as the *.r file of the first window.

Does anybody know what this means? Is the mentioned buffer sysa related to my table sysa or is this just a coincidence?

Thanks in advance
