Some time later on a work mates computer I saw him running 10.5. He usually runs the pre-release but told me this was the release, but it was not automatically updating. I check it out on Opera.com and sure enough it was released on the 2nd March. The day was the 16th so I tried checking for updates, but was told I was up to date.
I therefore went and manually updated at work, but was not so happy with the release yet for home. Sometime early April it began prompting to update at home and I did. I can see why the staged release was done. To me it still has some stability issues not seen in the previous version. On Windows 7 however, I now enjoy Opera with Aero Glass, as well as Aero Peek and Jump Lists. Now, you can easily access your Speed Dials, tabs and more from the Taskbar. And it is faster than ever. So well worth the update. Well done to the Opera team.
