Hey I just bought a new laptop, it has Windows 8, and the desktop I have is on 7. The previous laptop which died was also on 7. I downloaded the latest version Tortoise SVN (1.8.1) on both the the new laptop and 7 desktop, to checkout a repository and it works completely fine in 7, and will not even connect on the 8 machine. I can't find any known issues that seem to relate to this.
Any help would be appreciated!
