I was able to recreate your problem (BUG).
I started V19 (64Bit).
I drew a couple of overlapping rectangles.
Activated the "P" tool from the Special Tools flyout.
Clicked on a rectangle.
It turns green and has the icon, but no Geometric Parameters dialog or error message appears.
If I use the "Show Desktop" to Minimize all apps, then click on TurboCAD, the missing dialog pops up.
This still has some kinks that need smoothing out.
