I recently upgraded to SW2014 sp3 (64-bit) and find that in Simulation if I rename a remote load to something more meaningful, then edit the remote load and 'tick' to accept then the name of the remote load reverts back to the original default name. Renaming of other loads (pressure, force etc) is not affected. I've never had this issue on previous versions e.g. SW2013....has anyone else experienced this? I am also experiencing frequent short pauses during commands and slow "file opens" but I think that is a separate issue.
Verified on same platform, both with you model and fresh one made up. Nothing in KB yet for SPR's, shoot it to your VAR.
