I now have to do it too. This is only one particular class, and this problem appeared only today. I added another class in the library, I made other changes as well, but I don't understand, what may cause it.

BTW, may these lines cause troubles?

IF pemstatus(thisform,'hasnavstand',5) and thisform.hasnavstand
	thisform.navstand.navupdate()
ENDIF

BTW, clear classlib addrstd.vcx in command window didn't help and clear class too. Only clear all does. I was thinking about clearing in a form, but since none of the command worked, I should leave it :(
