Why?

[Zalmaxis]

Every time i enter zDC++ my computer start to move like really slow.
I reinstal windows and the problem is still there.
Why is this happening and how can i fix it??

 

[bla!!]

DC++ since about 1 year ago started using Tiger Tree Hashes. If you've added a huge amount of new files to your share, it will take a while to hash through all your data which uses up quite a bit of resources.

I'd just start it up at night one night and let it go.
