No idea why, but iirc it always was like this.  (that applies to 
breakpoints too)
double click => jump to code
current => set the frame for inspection

Years ago the debugger would get all watches before it could do any 
further action, if "current" was changed (and with many watches this 
could be very slow). So if you would double click, several frames, to 
find the one you are interested, you would have a lot of waiting time.

Now the debugger, can continue even if there are still watches to 
inspect, so it would be faster.
Maybe double click can (optionally?) include "current".

------------------------
Not sure, if in case of exception the correct frame is selected (ideally 
not the one in fpc_except).
This is sometimes one frame off, because some methods in RTL have no 
stackframe.
