MenuMaker in DW MX 2004 not shown when insterted

I've been working on it for weeks and now it's about time i get things right with some help.
Here's the catch.
I have a index page with 3 frames. Mainframe, topframe and leftframe.
In the leftframe is the menumaker.
I insert it in the indexpage on the left side of the screen wich is the leftframe.
I save all as frameset indexpage and also the leftframepage.

When i click on the indexpage nothing. When i click on the leftframepage bingo.
When i open the indexpage in Firefox or Internet Explorer all is ok.
When i close DW and open again (even while cleaning the tempfiles) nothing.

It drives me nuts.

No matter how much i like Xara, this is driving me to the compatition .......

Anybody can help with this one.

Thanks in advance.
