I'm not sure if it's reproducable.
When I have multiple files open in the editor, and I switch from one to another, it takes a half second to switch. Literally.
When I save a file, C::B locks up for 5 to 10 seconds.
It happened either between 1710 and 1717, or because I just turned on Code Completion's follow includes option (cache is off).
Edit: Wow, I built 1717 but I forgot to copy the files to my Program Files directory. So I'm actually running 1707. Silly me! :lol:
This is FIXED in somewhere between 1707 and 1717 (probably 1711).
