    Default ASSERT "!activationRecursionGuard"

    Hi,

    I have a pop-up menu which has an option to view a text file from an FTP server. When I click on this option, it calls a function which retrieves this file, then displays it. While I'm waiting for the FTP job to complete, I periodically call ProcessEvents(), to process events from the mail GUI thread.

    Since upgrading from v4.3.1 to v4.5.3 of QT, I get the following ASSERT If I try to bring up the pop-up menu again, before the file has been retrieved from the server. Does anyone know why, and also how I can work around this?

    ASSERT "!activationRecursionGuard" in file widgets\qmenu.cpp, line 961

    cheers,

    David
