Visual Studion 2013 Professional - debug a HTA?

Hi,

I am trying to debug a HTA as in step through it line by line - like I can
with C# etc.

I am using Visual Studio Professional 2013 and although I can open the
project and launch my App - when I try to set a break point VS just
ignores it.

I start the process of by doing open Web site and then choose a directory on
my machine. It then presents the files in the directory

Then I do either:

Debug - Start Debugging.
Debug - Step Into

And it opens the HTA and executes it. Internet Explorer is the emulation option
I have set.

So any suggestions on how to make this work?

Thanks,

Ward.
