"." in Combobox with search

The “.” (dot) is being replaced by " "(space) when i type in text. What can I do to solve the problem ?

P.S. Thanks form wonderful component

Combo box uses regexps for filtering, as result “.” act as any char while auto-search
You can locate  next string in dhtmlxcombo.js
     try{ var filter=new RegExp("^"+text,“i”); } catch (e){ var filter=new RegExp("^"+text.replace(/([[]{}()+*\])/g,"\$1")); }
and replace it with
    var filter=new RegExp("^"+text.replace(/([.[]{}()+*\])/g,"\$1"));
it must create correct regexp in your case
