My friend downloaded the Windows Beta 7 wallet and as you can see in the picture he is stuck at block 460.000. Also the "out of" blocks statistic keeps jumping between 663,000 to 1,000,000+.
Even when shutting down and starting again it stays the same.
Any advice appreciated. Thanks.
Could very well be a bug. Problem sounds similar to this issue. Have you checked peers/network connectivity and tried running wallet/resources/nodes/geth/geth.exe to check for errors?
This is an issue with windows, which is already fixed in geth#develop branch. Please wait for one release after homestead. This one will then include the fix.
Optional you can build from the develop branch yourself.
