Will be -rescan option in GUI?
No. Unless you're changing your wallet outside of bitcoin, rescanning isn't necessary.
ptmhd, so as you did a dirty installation - you have to remove
libeay32.dll and
mingwm10.dll manually.
I also did a dirty installation (are we talking about Windows? I am), and I didn't notice this problem until after I renamed these two files, and now I see the same problem after restoring them. There seems to be some "ghosting" of windows on top of the Bitcoin client. I'm not at home so I didn't get to look into it much, but it seemed strange. Maybe I just need to reboot. Anyone else getting this?
