Maybe this is just me being stupid, but I do have a few problems regarding the code completition:
1.
When I write function names, the completition box will pop up. If I select an element with tab or enter, the function names is completed - however
1a) Parantheses are written after the function name, the cursor is inside of them. There is however, no box showing the prototype - this appears to be the case when I call member functions of one class from member functions within the same class, and also when the prototype box disappeared before - see 2.
1b) No parantheses are written after the function name, I can write them myself though. Now the prototype is shown.
2.
If the prototype box actually shows up, it disappears if code completition for one of the arguments kick in or I hit backspace. I can't get it to reappear again.
Those feel like bugs to me. Though I still posted this here in hope of it being just a screw up on my side that is easy to fix if I correct some settings or whatever.
Oh version is 10.05 if that helps.
