Slackware :: Mouse Behavior In KDE4 Konqueror

I installed 13.1 last night and started playing with KDE4.4.3. I'm talking about Konqueror as a file manager only here. My default view is to have the folder tree in the left pane, with a detailed view pane on the right. In KDE3, I use the "Tree List View".In KDE3, I had my mouse set to "double-click to open files and folders". However, in KDE3's konqueror, you could still navigate the folder tree with a single click. One click on a folder in the left pane would show the folder's contents in the right pane, or a double click in the left pane would expand the tree to show subdirectories. I could still single-click on files in the right pane to highlight them without opening them.

In KDE4's konqueror, it requires a double-click to do anything with the folders, either to display in the right pane or expand the tree. It's a lot more effort just to get around in the folder tree. I found the Mouse setting in the System Settings that changes overall single-click/double-click behavior. If it's on single-click, it's easier to navigate the folder tree but then I end up opening files I don't want to just by trying to highlight them with a click.I dug through Konqueror's settings in both KDE3 and KDE4 but couldn't find what gave me behavior I liked in KDE3 or how to duplicate it in KDE4. In KDE3, the system setting is on double-click, but there doesn't seem to be a konqueror-specific mouse setting to customize it. Anyone else notice this? Is this hard-coded into konqueror, and it changed from 3 to 4?
