Hi oldturkey03- Basically, the difference is that you are saying that the TP won't open the file because the relevant application is not installed. That may be the case sometimes. But the TP also has a more fundamental fault in that often it will also not open files for which it does have the relevant file installed. For instance, it oftens happens when trying to access pdfs when Adobe Acrobat is installed and .doc files when Quick Office or a.n.other is installed. As you correctly say a file extension (.doc, .pdf etc) is associated with a file type, so that your browser knows how to work with it. But with the TP is will often download the file with an .aspx extension instead of interpreting the file correctly. The .aspx (Active Server Page Extended) file extension stores script and source codes that allow web browsers to translate and open web pages. Virtually all web browsers can 'decode' the script and then use the correct application to open the file. The TP browser fails to do so. Instead it just...

oldturkey03 - unfortunately that is not the answer. On the HP Touchpad there is an issue whereby the browser will not open some files that is DOES support and generates the MIME error. For example .pdfs. Most of the time .pdfs do open, but fairly often the MIME error results. The browser doesn't recognise the file type (even though the same file from the site will open no problem on other devices). The only way to then open the file is to browse to it using Internalz and add the correct file extension. Then click and it will open. Basically the Touchpad is not fit for purpose.
