Pop-ups within Training courses

Random pop-ups advertising undesirable content/products are more a
feature of random web surfing than of going to a known location for a
specific course.

Unfortunately the web is being destroyed by the "solutions" to unethical
behavior.  So, while a pop-up may be a good idea for training, default
browser settings have annulled it as an option.
1. Microsoft has set their defaults to disable all cookies from
non-Microsoft sites.  Cookies can be very useful for training that is
taken across several sessions.
2. Microsoft has set their defaults to disable "Active Scripting" (aka
JavaScript) while at the same time enables "ActiveX Controls" (aka the
mechanism by which spyware installs itself on your computer).  Without
JavaScript, you have to use plug-ins (like ActiveX or Flash).  ActiveX
should be disabled because it is a really bad security risk.  It is
designed to seamlessly merge Word, PPT, Excel, Outlook, etc. with the
web/outside world. Of course since you could write a complete operating
system within Word, this opens the door.  Java, on the other hand, is
designed to not allow the web into your hard drive, but it is getting
really hard to deploy because the MS operating systems avoid supporting
it.  The newer MS-operating systems are easier to lock-down, making it
impossible for a regular user to install the plug-ins.
3. e-mail filters/spam blockers are blocking lots of legitimate e-mail.
 Many spam blockers don't let the sender know about the blockage, so
there is no way of knowing if your e-mail is being ignored or if it
never arrived.
