Hi, I added a couple of shape data to a shape (Server shape). I recognized that my labels are switched in lines. Like I define a label called "IP address" it used to be in line 2. Sometime in between it moved to line 5. Don't know why. But some more strange things happened. I defined a label "data centre" I gave it a type "fixed list" and entered some info's there. Everything looked fine I checked OK and in between again I recognized that my type "fixed list" was gone. The label was still there but the type changed to "string" and my values are gone. Every time I try to fix it back it won't take my changes. I don't get any error messages that I entered a wrong value or wrong spelling or sort of that. Some other labels were also switched back from fixed or variable list to string and the data was lost also. There seems to be no pattern why this happens. Any idea? The system is a German Windows XP SP2 (fully patched) laptop machine. English Office 2003 SBS SP3 (fully patched) and English Visio 2007 standard (fully patched) installed. Thanks for help. Kind regards Chris
