"library is locked" but it isn't

[PaulG.]

I have a typdef cluster that I want to edit but cannot because LV says that the data type is in a locked library. But the library is not locked. As far as I can tell I have no locked libraries. RT cRIO system, LV 2010. Thanks in advance.

Never mind. I saved and exited the project. Re-opened the project. Went back to the control. I was allowed to change it. Seems like a really clunky way to get something done.

There is a lot of strange stuff like this with LabVIEW. For instance, my coworker the other day was creating an X control and none of the Properties VIs he was creating were not showing up in the project as he created them. He thought there was somethign wrong, but then he hit F5, the project refreshed, and they all showed up.
