Tablet Error (code 101) when trying to capture a signature

There is a known issue with HTML scripts which have been downloaded over the Internet or received via email.
Windows recognises them as a potential security threat and places a block on the file itself. The block can be seen by right-clicking on the file name in File Explorer and selecting properties as illustrated in the screenshot below.

Solution

There are 2 solutions:

1. The easiest one is simply to click the "Unblock" check box, click the "Apply" button and restart the browser.

2. Alternatively you can edit the file with a text editor such as Notepad and save it with a different file name - the process of saving it with a new file name removes the block. Note that simply renaming the file does not unblock it.
