What is actually problem with the wallet? I dont have problem with 0.3.2.1. on Windows 10 64 bit
Here you can see the current bugs.
The Windows wallet does work pretty fine, but there were some freezings and crashes reported earlier in this thread. I have a Windows and a Linux wallet. My Windows wallet had no freezings, but I'm not using it very often.
The most severe bug is that the Linux client gets stuck at some blocks, and there is no way to download the block in question other than copying a blockchain snapshot (blkindex.dat/blk0001.dat) from a Windows client to the ".slimcoin" folder. So the best way for Linux users on desktop PCs is to use the Windows client via Wine.
