Hello

I've installed protoshares-qt (from protoshares-0.2.0.zip, "About" shows "ProtoShares version v0.8.5.0-unk-beta") at 29 November and it run since then pretty much constantly (I started mining in the same time - not with built-in miner since it is slow - so PC had to be on all the time).
After short initial trouble with establishing source of blockchain it loaded and worked smoothly showing constant ~8 connections to the network.
The problem is I started to notice that although pool announced payouts in regular intervals and looking at transactions online showed those payouts, only first one showed in the client. I exited the client and immediately run it again and it showed I'm 24hours behind the network (despite it showing all up to date and running a moment ago).
After that incident I had to restart the QT client many times, otherwise it would fall behind.

In debug.log these events look like this:
 - first there are many
received block 000....
ProcessBlock: ACCEPTED
CTxMemPool::accept() : accepted ...
 - and also
received getdata for: tx ...
Commiting ...
SetBestChain ...
 - etc - in other words normal blockchain updates

 - but then at some point:
trying connection ...
connected ...
send version message: ...
 - or
connection timeout
 - and these can go on for hours or even days until I restart the client. All this while the tooltip shows I have multiple active connections to the PTS network.

I've looked on various forums and it seems like I'm not the only one with this problem but I haven't found anyone with the solution or even hint to what might be wrong, so I finally decided to join this forum and share the pain
