I'm running kde 4.3.5 opensuse 11.2. I have my mouse settings to use 'single click'. Everything works like it should on my desktop and when browsing in dolphin, but when I make selections in, say, the Personal Settings menu, I have to double click to open a sub-menu. This behavior also happens when I am trying to save/open a file and I try to navigate through folders. I'm not sure what happened but it didn't used to be like this. Any thought?
