In the middle, well nearly the end wouldn't you know, of a project AC13 (latest fix) has suddenly started to crawl particularly:
1. Going up and down between stories.
2. Deselecting selected items in sections.
3. Redrawing plans after zooming.
I checked and hardware acceleration is off and memory is at max, I have 3Gb on board and I have done much larger projects than this one without any problems.
There is at least 330GB of free space on the HDD
I have checked and verified permissions.
The only other programs running are Mail and Safari and switching them off seems to make no difference.
24" iMac 3.5 years old with a new 1 TB HDD last November.
2.4 GHz Intel Core 2 Duo
OSX 10.6.7 SnowLeopard latest update etc.
Any ideas would be appreciated.
