Quartus II lagging for no reason

[Altera_Forum]

I've been changing the names of some of the input ports in my circuit, and after saving Quartus lags at an intolerable rate. Scrolling takes five seconds to respond, and I can hardly change anything. What's wrong? How can I fix this problem?

I suspect the problem is with your computer rather than Quartus.

Quartus works relatively fine at all other times, it doesn't lag horrendously until after I had switched the name of the ports around.

If you are using Linux, you might be having the same problem I've had. See http://www.alteraforum.com/forum/showthread.php?t=4615.

Ah. Well I am using Fedora 9, though I've never experienced this problem besides today when I was switching around names of ports. I really hope Altera resolves this. Thank you very much for your help, I wasn't expecting that anybody would respond.
