I have no idea why this might happen, what I would do if this was happening to me is
- Close SW and restart my computer
- Open all part and assembly files that the drawing relates to
- Use the freeze bar in the parts to stop SW from trying to rebuild the part
- Make sure that "verification on rebuild" it unchecked under performance in the options menu
If this is causing you a lot of trouble do a pack and go and send the files to your VAR for them to have a look at them. If the same thing is happening for them they can send it to SW for analysis.
Is it just that file or do you experience it with others? What is the file size?
I have a similar problem occurs about 10-12 times a day with different files. I close SW and reopen SW and it peps up again. Thinking I have a bad install.
You may as well. Try to repair off the SW disk. That may help. Otherwise it might just be a quirk in the drawing file itself. Try a save as and see if that helps.
Thanks for the replies. This drawing is laggy across multiple/different computers. I was able to solve the problem by deleting and then re-inserting the title block. But I would still like to know how the problem happened as I am in charge of debugging solidworks...
