very sluggish despite fast 64-bit computer with lots of memory

For many years I have been working very satisfactorily with Jasc Paint Shop Pro. 9
Unfortunately, this program Win7 the bug that you can select when printing any printer. It is always output automatically to the default printer. Since this has yet bothered with the time me, I switched to this program.
Only me has disturbed the black background layout. But then I remembered that colors come across better / richer in contrast, if you hold the black background.
Meanwhile, it bothers me more and more, because the buttons look like covered with stealth.

But what I do not understand why everything is so slow ???
For example, the Crop:
under Paint Shop Pro 9, I can click on the edges and move without inertia.
On the new X6 everything wobbles as on a limp rubber band afterwards. To do this, of course superfluously again abundant settings, all of which are updated as you drag.

What is this Überfrachterei ???
Where have remained the slim fast programs?

It make no more fun to buy new program. Everything is overloaded and every idea that any good for holding is converted.
The same with the new Office programs. The old were more nimble and less sluggish.
