Thank you for your replies, finally, I get the new version of Multibit!
Today something of strange happened... The total of the wallet was 0,50 when I know a 0,05 max in this wallets.
Maybe, and old version of Multibit don't have never sync correctly? (My first think)...
I try to send to another wallet, but it say 0 node...
Try again and same issues... I decide to sync again and it show the "correct" fund (obviously) 0,05.
Actually when I received a payment it don't refresh, I have to make another sync (this make me sadly)...
It's a problem of my internet connection? Pc setting? Multibit setting?
(I have a connection really bad taht sometimes go off line every 5 - 10 minutes.)... (this make me so nervous)
Any suggestion? Multibit-Hd is much better and faster?!? Is likely better for my actually situation?
I find with classic sometimes you have to wait until the transaction confirms before you see it in the UI.
