Actualy i wrote to soon, didn't notice straight away. There is a problem, something is wrong with the list keeping 100 items after a search.
Setup
Global history limit 100
username (misnamed GlobalDropdownLimit . set to 45)
Config
SearchEngine searchcount=100
SearchEngine searchvisiblet=100
(the above i have set to all search engines)
GlobalSearchHistoryLimit=100
GlobalDropdownLimit=45
When i open altbinz all is ok and list extend the screen height downwards, and scroll of history working. Next i do a search and after all past history is gone and only remain is 45 items on history list. Another search and bumps the list downwards (new search added then 44th becomes the 45th on the list, old 45th is disappears).
I made a another backup of config as when close altbinz the list is shortened to 45 items only. Seems to having a problem with knowing and remembering 100 items on the list.
btw the list wasn't full (100 items) there is about 80 or so on it.
Have tried altering config and setup, doesn't seem to take so works as it should.
