It shouldn't use much of any cpu power if any at all when typing. 

However when I type and the CPU usage goes up to 100% there is a lag time when the letters are typed (it's not instantaneous).  As an example if I was typing writing a procedure or something, by the time I finished typing proc the letters o and c would not yet be up on the screen literally it would take 1/4 of a second for each letter to appear.  As you can see if I was typing in a long line it would lag far behind just a couple of letters as I am seeing on my laptop which definitely indicates a problem like a keylogger or a virus of some sort. 

At 20 or 30% it shouldn't really matter that much but in all respect, as Roman has mentioned, why should typing a character on the screen consume any CPU power at all?

It doesn't have to be real typing just any set of keys as fast as you can so my benchmark is probably roughly the same as yours.  Probably some bug in my laptop or something I'll have to wipe the drive or something as I have no virus software or firewall then again I don't hook that one up to the internet at all. 

As for CPU usage, do you think 15-20% is a bit on the high side just for typing something in?  Shouldn't it hang under 5%?  Also strange that Classic uses more CPU  than the standard GUI.

My mistake.  Even the student helping the drunk to his proper seat may already be taken.  On top of that, what is the probability that he even decides to help the drunk to his proper seat?  Then again this isn't a question with intelligent design in mind.

"Maple" leaves ... from Canadian maple trees.  Or in the current sense of company ownership the Japanese maple.  Either or it's still a maple leaf.  I'd keep it as the most suitable symbol.

That's a bit disappointing.  Maybe it's something they(maplesoft) need to think about.

Thanks for the info.  It would be nice if someone put out a quick review of Aladjevs library package. 

And are these the only two major non-maplesoft add-in packages (Maple Advisor Database and Aladjevs library) aside from anything available on maplesofts application center?

I forgot to add the results in the initial post.

Maple returns

Error, (in Statistics:-Mean) unable to evaluate x to floating-point

So it seems that Maples routines cannot handle a list that includes a variable, however ...

and from the stats package from Karian and Tanis returns

2/3 x + 4/3. 

Not sure why Maples standard routine couldn't handle that?

Would be easier if the page break lines could be toggled for pdf pages. 

The print preview tip is a nice work-around, but still a bit of a hassle.

If I don't use page breaks, how do I know where a pdf exported page is split up from the maple worksheet?
