Hmmm... so, from what I'm getting, you click the "Send" button in other themes rather than "Default" and nothing comes up. In Firefox, nothing happens, but in IE, you get those errors (I'm assuming on the viewpmsg.php page?).
There might be theme-specific javascript of some sort that is interfereing with the code that would launch the pmlite.php page. Javascript is pretty touchy; just one little syntax error will throw off the whole script! Unfortunatly, I can't test this for you to see if this is the case because my XOOPS site is live right now.
Other than the possibility of a Javascript error, I'm honestly not sure how to diagnose this problem. I personally haven't had a problem like this before. Check the template for the page and your theme for Javascript errors. You could also try rebuilding the template file and/or contacting the creator of the theme you're using for troubleshooting the theme.
Let me know how checking the template files and javascript goes. I'll see if I can get my hands on the theme files and sort through them.
Well, good luck with your site!

EDIT: So, I looked at the dream_on file to see what might be going on and I found that the theme's theme.html file is missing <{$xoops_module_header}> in the header. You could try adding that into theme.html in the header section and see if that changes anything.
