There is no category for this problem. But the devzone has great information but a horrible user interface riddled with headaches.
1. Pet peeve #1: Trying to enter tags - type a letter and get a long list. Type a second letter and you hop to something totally different. First letter ignored.
2. Pet Peeve #2: Several drop downs need an 'other' option, including tags.
3. Pet Peeve #3: When looking at a particular thread, the 'reply, etc.' options are often missing and in many cases present for some comments but not others (usually the last comment is the one with missing options). There is a workaround on a PC with a task bar that can fix - this someone on this site figured that out. It is annoying to have to do all the time.
There are plenty more but I do not stumble upon them with the same frequency as the above three.
Since this site has such a wealth of information it is a shame that its UI has so many shortcomings and defects. Can the web developers fix some these issues please!!??
