In Ver 8xx there is a problem with quick search, if anyone has noticed. In version 7xxxx (not the latest beta), you could make a new , search, in all ready results that you had made before.
For example i want to search "Mr John's" replies about "Box". First i was searching for "John" and after for "Box". Now i can see all sendre's with a subjet "Box".
In previous versions 7xxx it was working very well. After the latest versions of 7xxx and now in 8xxx, it doesn't work. Even in this version they didn't fix it.
