Frost 0.9 - At least it does for me. I began to wonder if you guys put up a bet to see if I saw this 
Adding any applicable modifiers to the Frost Base object removes the Icon from viewport.
No more clicky clicky only H select by name when enabled in viewport is deactivated 
This was answered elsewhere already. A modifier on top of Frost changes its class on top of the stack to Editable Mesh, so it is unable to draw its icon.
Btw, the same applies to pWrapper.
The Krakatoa PRT objects don’t convert to a mesh though, so they preserve their icon.
Sorry, I hadn’t seen it mentioned, of course I haven’t read every Frost post 
Thank you for the explanation. I shall consider the case closed and cease and desist.
