> Your FAQ states: "The only registry keys the tweaker modifies are it’s own settings."

This statement only applies to the non-portable version.

The portable version uses an .ini file to store it's settings.

> So -- even though I didn't wish to remove 7tt from C: drive -- I find that I must uninstall 7tt from HDD before I can then choose Portable mode after restarting 7tt's installer;

Unfortunately there is no option for portable installation in case the tweaker is already installed on your PC.

One workaround is to use the /portable command line switch, but it's probably not mentioned anywhere.

I've added it to the FAQ.

A "fully" portable version is available, read the FAQ for more info:

Sorry, but I don't understand what the suggestion is about.

A screenshot could help.

> When I substituted ... for the aforementioned Target, it would not apply.

What do you mean it would not apply?

> So I dragged the existing desktop shortcut to the startup folder . . . and added " -hidewnd"

That should have worked.

Did you also remove the checkbox from the settings?

Otherwise it's possible that 7TT starts up twice upon boot.

Such option already exists:

"Don't show jump list when dragging a taskbar item towards the desktop"

There's an open ticked about the issue:

http://tweaker.userecho.com/topic/179603-decombining-options-dont-work-as-expected-with-the-combine-when-taskbar-is-full-configuration/

While it might be possible to improve the way it works, for now It doesn't work that good, and I'd suggest to avoid using both options simultaneously.

I don't know why the tweaker's startup entry gets deleted from the registry on your system, but the issue with the tweaker's window showing at startup should be easy to solve.
