I'm an Opera & OD+ fan too, but I haven't seen this behavoir you describe. Could be because I don't open multiple Opera windows, I use the tabs.

I don't use Opera but I do use Audacity with Object Dock Plus without any problem. This is reaching a little bit, but as I read this I wondered if this is the same type of video conflict discussed in another thread in this forum, "PowerDVD andOD+", sitting down at eleven days "Replied" date here.

Easy way to find out: Move any docks you have on the left side or the top over to the right side or the bottom, see if your problem goes away. If it does, then you can either leave the docks moved or try disabling the "magnification" feature which seems to get in the way sometimes. Also, I've had very poor luck with any docks wedged in the upper left corner of the display, i.e., "Position:Top / Alignment:Left" or "Position:Left / Alignment:Top".

Let me know if this does the trick.

I've noticed that if ObjectDock is loaded, it causes Opera to refresh the page when you switch from another application. If I set in Opera Tools/Preferences/Advanced/Browsing 'Loading:Redraw instantly' instead of 'Loading:Redraw after 1 second' the page appear faster.

But the switching cause a cpu overload (36%), because Opera redraws the page. If ObjectDock isn't loaded, when I switch to Opera from another application, the cpu remains nearly untouched (3%).

I've deactiveted 'Represent minimized windows by their screenshots' in ObjectDock preferences. It's the same, no changes.

I'm not sure... I did have a similar problem with an old computer a while back. I wasn't using OD or anything, but smooth scrolling in Windows would kill the response time of the program.

I'd believe you about it fixing the problem... but I can't say that it makes a difference on my machine.

I found that putting the Dock at the top of the screen rather than the bottom solves the problem rather nicely. I would guess that it's because Opera isn't trying to redraw the top area of the screen very often and so it doesn't lock up like that.

I have to say, I don't really have a passion for the dock at the top of the screen, as it often obscures menus and toolbars in other programs. I guess I can live with it though, unless someone else finds some other way to fix the problem via Opera preferences.

Contrary to one of the solutions listed in the "PowerDVD and OD+" thread, the overlay issue can't seem to be fixed by starting one app before the other in order to let Opera claim resources first. I agree that it sounds like the same sort of problem, but I was unable to draw up a solution based on the comments in that thread. They mentioned the position of the Dock a lot, but it didn't seem to be relevant to the fact that the Dock was actually ON TOP OF the display in PowerDVD.

Thanks, all, for the replies though!

It might help to exclude OD from Anti-Virus software scanning. I did a while back, and OD got speedier, and it may be why I don't notice any problem with Opera. If you want to try this, be sure to exclude OD in C:\Documents and Settings\USERNAME\Local Settings\Application Data\Stardock\ObjectDockPlus
