Unable to save copied toolbox-part

I have a custom part in my toolbox that I've made andinstalled. When I Ctrl-drag it to an assembly and click the greencheck-mark I get the following message: "Unable to save document'C:\Solidworks Data\CopiedParts\tmp00015648.sldprt'". The file is,however, created in said folder.

When I dismiss the message, the inserted part is deleted from theassembly.

If I drag the part into the assembly without holding down theCtrl-key, everything works normal. Standard parts (screws) works asexpected when Ctrl-dragged.

PS: Ctrl-dragging is to get an individual part file when insertingtoolbox parts in assemblies, as set up on page 3 of the toolboxconfiguration dialog.

Anyone have any idea as to what happens?

I am using SW 2009 SP3 on Win Vista 32-bit.

Thank You...
