I browse all the menus, but I don't see when is Volkov Commander loaded.

If you use DCC, Volkov Commander is disabled (they both use the menu item in the "Advanced Utilities" submenu).
This is normal because they both perform the same function and DCC is more capable (so it overrides VC).

how to make the dcc working good wiht 15 tft screen? it seems to lose the first line that contains the main menu...
I think Doctor XP should add instruction for configuring dcc in order to work properly also on TFT screens. I had take a look at the option of dc and there is one that is referred to tft screen...but, How to use it?

Try to configure DCC to use screen size other than the standard 80x25 from the Options dialog, this may solve the problem.

Doctor,

It should be clearly stated when using DCC, Volkov is omitted,
When using Drive Image Center, Drive Image is omitted,
Partition Magic and Volume manager,
etc...

I should do that, but remember I'm working solo, so taking care of the documentation in addition to the real batch files is a very time consuming job, and I'm very very very busy.
