Hallo!!
    When I try to compile a modified version of Monodoc source code, I
get this error:

./browser.cs(257) error CS0019: Operator == cannot be applied to
operands of type `Monodoc.Tabs' and `object'

The code that fails is:

256://Add the Tab
257: if(tabs == null) {
258: 			tabs = new Tabs(tb);
259:} else {
260:			tabs.tabsList.Add(tb);
261:}

I solved the problem doing this:
if((object)tabs == null) {

But I don't know why the compiler can't compile the prior version. The
tabs variable is a reference to an object of type Tabs that inherites
from Notebook. So, where is the problem?

Oh, I should mention that: Mono compiler version 1.1.1.0

Mario.
