It already works like that on the first succesful attempt in Pre5, I'll have to test in Pre6. I think I might have clicked on 'No' too soon, sorry. I think my Bard had that skill and I recall it working correctly in Pre6.

Unless I'm missing something, in p6 it seems to work as I described. I just verified this with two new characters. Once you've detected the trap on a door you need to Detect traps a second time to ID it properly.

Of course it might be that I'm being stupid, in which case I'd be happy to be set right, I'd love to be able to avoid the extra keystrokes.

My appologies, I was caught up in other matters, but:

I can confirm that what you are requesting is already the case in Windows XP Prelease 6 using a Level 2 Human Thief on I:2.

Sorry, I should've mentioned in the original post that I mean the Detect traps as used while searching, because for some reason it works differently from directly applied Detect traps (which works on the first go as you said). It just didn't occur to me that anyone would apply Detect traps from the skill menu on a door, since continuous search ("ws") does the same thing much faster. Thanks for pointing this out, I'll amend my first post to be more clear.

However, I still think the traps discovered by searching the door should be identified right away, just like with applying detect traps from the skill menu.

Some Spoiler, but not too serious, you might appreciate

The manual entry for Detect Traps states that "The 'Search' command also activates this skill."

It seems to me that all functionality of Detect Traps should be exactly the same, whether it was activated via Detect Traps, or via Search; or, if that wasn't the intent, then the manual entry should be clarified.

I'm changing my vote to yes.

Fixed.
