This is weird and i have no idea where to fix it.
When using Firefox, Chrome or Safari on my site http://elite.zappowee.com and I'm editing a post, when i try to insert/edit image or edit html source they all try to download the appropriate .htm file.
Not just me I've had other people try it and the same thing happens to them.
I get the pop-up window and then instead of getting the program running in there i get the download file dialogue box.
The even weirder thing is it works fine with IE. I never use IE but out of frustration i tried it and it works fine.
I don't know what it is because I'm using the same browser to type this post and those buttons work fine on your site.
Attached images shows what i get.
