That's... When creating a DDE reference from new to a part (say a cell) in another file (say a LO Calc file) if there are spaces in the file reference the file reference of the DDE only is stored till the space (and, of course, the DDE link doesn't work). If you complete it manually, then it runs properly (but inestability is verified requiring closing Windows XP Session for restoring all LO process... maybe browsing Task Manager would be enough; not checked ;-)
Maybe related or maybe a new one: if you DDE link to a numeric value cell in a LO Calc number-formated with text in the form "pre-tesxt "0.00" post-text" the DDE link becomes blank.
I assume Kohei knows about this stuff, and can perhaps resolve this as duplicate, it sounds familiar.
