--- Comment #6 from Nikolay Sivov bunglehead@gmail.com 2012-01-29 15:54:28 CST --- So it does:
--- 002f:Call KERNEL32.WinExec(0043d78c "explorer.exe "http://gunz.ijji.com/?from=desktop%5C%22%22,00000005) ret=00406832 ---
after that parse_command_line() misinterprets argument string - it skips first two slashes looking for known command switch, doesn't find it and what is left is a part after '?':
--- 0031:Call shell32.ShellExecuteW(00000000,00000000,0033f740 L"?from=desktop"",00000000,00000000,0000000a) ret=7ecacb10 ---
that's a helper that should be fixed.
