According to this document: http://www.techsoft.de/htbasic/support/dde_man.pdf
Default timeout for dde connections is 20 seconds.

As described in the bug report, this happens when an new soffice
process is used to start the macro. So I have a theory about that the
new soffice process blocks the DDE activity of the main soffice
process for 20 seconds, and when it times-out, the macro call to
DDEInitiate is allowed to continue.

Is there anyone who could help me with some brainstorming on which
tactics to use fighting this bug?
