Well, I've just read sth to get know what HTAs are and what I think at the moment - that's impossible.
First of all, you should know what for you're writing an application and in addition you won't be doing it for sites that you don't know. For me it's quite obvious that it won't work. But if you want it, you can always ask webmaster of the site to remove error from his page
Another thing is that you can add
trusted=yes for the iframe or frame tag but in this case that won't help much.
READ THIS:
"Frames and Security
Since HTAs run as fully trusted applications, certain security precautions are necessary when HTAs use Web content that is not equally trusted. While the HTA is free of all security restrictions, it is important to maintain the usual Web-security constraints for untrusted content within the HTA (as determined by the zone settings for the particular Web page).
Thus, for security purposes, a frame containing HTML within an HTA is treated exactly as it is within the browser.
On the other hand, in some cases a frame might actually be a functional part of the HTA—in which case it needs to be able to interact and do all the same things that the HTA itself can do. For instance, if you wrote a wizard HTA, it might be convenient to have an outer framework, with title and forward/back buttons, and an inner frame that defined the content for individual panes of the wizard. These frames would need to work as part of the HTA, and,
of course, only appropriate and trustworthy content would be put into the frame—certainly not content from any URL whatsoever.
The HTA container page defines which frames are, and are not, trusted by use of a special attribute on the <FRAME> or <IFRAME> tag that is unique to HTAs. By specifying
TRUSTED=YES, the HTA infers all of its privileges upon the content it navigates into the frame. Absent this attribute or with TRUSTED=NO, the frame content is handled just like HTML in the browser. Since only HTAs can declare a TRUSTED attribute (which is ignored for HTML within the browser), it is impossible for untrusted content to assert trust it"

Hope all that information was useful for you. It took me some time to find it in internet
