Sorry, late response delay...
I was running only one wallet. Today I had to use second wallet , not at the same time and wallet file - (rebroadcast function). Using Windows 7 Enterprise SP1.
Restarting wallet helping only for progressbar thing (it is showing for 5 minutes synchronizing, but stuck at 0 hours).
Tried today about 5 transactions. have to rebroadcast all of them...Nothing changed on my computer. Usually it takes about less a second, but today much longer time (several minutes for first confirmation).
I will try new version from github, thanks fernando and all.
