I use Slackware, and I have the both -current and -stable on my machine. So I use KDE 4.2.4 and also use KDE 4.3.4 sometimes.
In KDE 4.2.4 dolphin always remembers the view properties of every place, even remote places (through samba).
But in KDE 4.3.4 that don't happens. In folders that are in remote places, dolphin use always the same settings. It don't remembers the view settings of that places.

Any one notice this? It is a bug?

This is likely to improve Dolphin's loading speed with remote protocols. If you wish to be able to do this, I suggest you file a feature request at bugs.kde.org.

I like the old behavior. Maybe there is a way to change it. I hope so.

I couldn't find a setting to this affect in KDE Trunk, so please file a feature request at bugs.kde.org.

I already reported it.
