I have just downloaded and installed SP1 and immediately I get crashes - e.g. when I double-click on a block to edit an attribute value
pick a grip to edit an entity I get "INTERNAL ERROR: GEDIT3"
pick the insertion point grip to move a block
etc
Sometimes this is followed by a system dialog box "Microsoft Visual C++ Runtime Library" Runtime Error! Program C:... R6025 - pure virtual function call
What is going on?
