Am I the only one with huge WE lag?

[Furkentine]

When I preform certain functions in the stock form of world edit I get huge lag (40-50 second pauses).
Functions like renaming or copy/pasting a unit.
Does anyone else get this or is it just because my computer? Thanks.

That's because they have to redo your palettes for the units, and rename every single unit on the map. This lag doesn't occur in the campaign editor, because you do changes that don't happen while you are working on one of the campaign's maps
