Running SW2008. When inserting a part into an assembly, I get the message "Open Clipboard Failed." I then try to insert the part again and it works. I used to get it occasionally, but since going to SP4 I get it almost every time I insert a part. Size of the assembly doesn't seem to make a difference. Any ideas????

Pentium D 3GHZ

Windows XP 32 Bit.
