Rather than adding a new thread each time I come across a strange quirk in W7 installs of Opus, I thought it might be more helpful and less messy if I post one thread, and others might be able to add or help in one place. I hope that's OK.
The quirk that prompted this post is one that I have been able to duplicate, and was one which I was watching for this time.
After answering NO to all the integration questions during the install (leave FTP handling alone, leave ZIP handling alone, leave default image/sound/video handling alone), Opus has defaulted to handling ZIP files. This is something I definitely HAVE had major headaches with over the past 18 months, so I wanted to post this minor issue here.
When I finished installing, which didn't require a reboot, despite asking Opus to start with windows, when I opened up the ZIP preferences page, the "Activate Opus ZIP file handling" is set to true, even though the next setting (use Opus as the default ZIP handler) is set to false.
My issue with this is that I manage my zip files better than Opus does (no offence intended), and it's actually pretty annoying when I double-click a zip file so I can open it and deal with the contents myself, and instead Opus opens it in the current lister. I'm not sure if that's what's intended, but that's what happens.
It's an easy fix, but it would be nice to not have to do that after an install.
The prefs dialog also seems to have problems painting the folders pane of the prefs (the left-most pane in the dialog). After closing up a couple of settings, moving the mouse over the list repaints some of the category names. I'm not sure if that's a W7 thing, or a video driver thing. My video card manufacturer (AMD/ATI) has just informed me that they have reclassified my (ex-leading edge) hardware as "legacy", which means any W7 support will be best effort only, and then only after their current hardware offerings are updated and debugged. But that's hardly surprising from the company who can't actually support their own products, and whose last response to x64 driver issues was "try third-party graphics hardware or software, not ATI, and no, I'm not kidding).
That's all to report for now, I'm going through the prefs and verifying that there are no filetypes or items that Opus has taken handling ownership of, and ensuring that it's not set itself up as the explorer replacement (so far, so good).
