The DecBy duplicates might be even OK....
Looking at the screenshot they aren't OK, they are just duplicates.
Ollydbg can you check why they happen, because I've seen it on my own code.
Using the CC debug tool(dialog), I just lookup the keyword "DecBy", and I get four entries, I found that they are all overload functions.
See image shot below:
So, if they have different documents, those document will shown in the right side of the suggestion list. While we move the caret in the suggestion list, the document will change accordingly.
My suggest would be: Merge the same entry in the suggestion list, but we need also merge the document.
Or, we can just leave it as it is.
