OS is Vista x64 Ultimate SP1
Spring Downloader 0.98.0.3
TAS Client 0.45
latest TA: Spring
8GB RAM
AMD x2 BE-2300 @ stock freq
nvidia 9600GT @ stock freq / 180.48 driver @ let the 3d app decide option
Another strange issue is when I close TAS Client sometimes gives a error and Spring Downloader (if it's running) is closed too
Any ideas?
Here is the error:

Edit: I realised that Spring Client crashes 'cause of one or more of 68 current widgets.
