I've been running Windows 7 as a work machine for a month or two now, currently on 7100.
I have XP dual booted. I have Opera on both. Opera installed last year on XP and a month ago on Windows 7
The bizarre problem, I copied over some profile stuff for opera to the Windows 7 install.
I booted into XP loaded up opera and all my settings were nowhere to be found, digged around a little and found that Opera was calling for the settings from Windows 7! c:\users\roaming\appdata blah blah blah.
Since that doesn't exist on my XP install, it created it's own folder there. I uninstalled opera, reinstalled and the default location to find the user data is mimicking a user directy from Windows 7? wtf is this about.
The XP and Windows 7 are on entirely different hard drives, I fresh installed Windows 7 off a usb disk. XP is 32 bit Windows 7 is 64 bit.
