Lately, I have been getting the following errors while running or attempting to run Tortoise SVN 1.5.6.14908 on my Windows Vista Business Edition.
So what I did was, download the latest Nightly Build from tortoise website and it solved the issue. Hope it helps somebody.
I tried digsby after looking at a Yahoo Ad. It took me half an hour to download, install, run, test and decide to uninstall it. It is really very heavy, takes too many notification icons in the system tray and takes LOTS of resources.
One of the things that I didn’t like was that it shows me more details then I need, e.g. one of my acquaintances got a post on their WALL (in FaceBook), like I care? It does not function like the normal FaceBook.
My experience was not too good so I dont recommend it to anyone. But if you are an enthusiast like me, go ahead and test drive it today 
Here are a couple of screenshots of Digsby
