after replacing the predefined dict.leo search engine with dict.cc sometimes still dict.leo gets loaded

[Kh4l3tH]

I used the predefined search enginge for dict.leo.org and replaced the url with dict.cc. sometimes when using the shortcut for dict.cc, the search is still executed on dict.leo.org. i have not found a pattern for when this happens, but its probably like 1 in 10-30 times.
