Did you click the path with the Alignment Tool before using the alignment buttons ?

I looked for it--no soap, as can be see in the attachment
   
Could the icons go into the void following Align (the bold one)?
If so--can somebody, please, recommend a combination of Theme/Icons optimal for visibility under Windows7?
-- I had to bar the default (dark) theme to recover most options in plugins--i.e., 'Simple Bilateral' and 'Multireplicate' (new version of the old 'Clone Layer') didn't show well.
-- Then, I switched to color icons because I couldn't distinguish among the monochrome ones on the light background, and inverting them made my eyes ache--yes, I am old, and with some eyesight trouble.
-- And now, it seems that I have lost some further functionality through missing/invisible icons...
As there are many combinations to try, and not all the tools show at the same time, any help will be appreciated.
Thanks!
