My YUM wallet client (Ubuntu 13.10) is stuck on 'Synchronizing with network...'. It says it has 'Downloaded 5726 of 493905 blocks of transaction history'. The number of total blocks remaining keeps increasing until I restart the client. My mining processes are generating hashes but I'm a bit worried that they're not making any difference as the wallet isn't synced.

The same is happening on a separate wallet on another PC (not mining). Any idea why this might be happening?

FWIW, I've added another 2 to try and help it get over the retarget hump.

My first post too. Not sure I get the need to send one post before using the other forums. The newbie forum just ends up as a collection of 'Hello World!' post with not much substance.

In any case, I guess I'll catch you all in four hours in the other forums.
