Thanks for the additional information Wrangler.
It sounds like there are two issues.
(1) An issue with the drop down menus.To make sure we're on the same page, here is an example of how it is supposed to behave:
http://www.youtube.com/watch?v=wJhiq9pUnZE&t=0m37sNOTE: A recent update changes the dropdown behavior a little -- if using a stylus or mouse, the tool-tip should not appear because it should be clear what's being pointed at. If using a finger, it should appear as it does in the video.
The item you underscore in red is not button and it does not need pressed -- it is a 'tool tip' that shows which option in the drop down menu your finger or stylus is over. It's there because fingers typically hide the option you're pointing at so additional information clarifying what you're pointing at can be helpful. However I understand that it visually looks like a button. If the system is behaving correctly, that item should disappear the moment you your finger or stylus is no longer touching the specific dropdown item — so if you try to lift your finger and touch that element, the element should disappear before your finger gets there — in fact, the moment you lift your finger off a menu option, that option
should be selected, and the whole drop down
should disappear.
There is no reason why a smaller screen should effect the dropdown behavior, though the interface is not well optimized and so a slower device may fail to respond instantly, making its behavior appear erratic.
If the dropdown system is literally behaving incorrectly, then there may be a deeper problem I'd want to address because it may also effect FF on tablets — though I'd need to know the specific version of Firefox, operating system, and the specific device version. It'd also help to have confirmation that the drop-down behavior is also broken in Chrome (and which version of chrome that is).
(2) An issue with zooming.I'm afraid I'm still not clear about the specific issue with the pinch-to-zoom behavior that you are encountering. Your followup seems specific to the dropdown behavior.
I do believe you though when you say there is something wrong and I am interested in what that issue is because it may affect tablets too. If you can better describe this let me know.
FWIW: I sometimes test on phone in order to expose weird edge cases that might effect tablet use. They kind of serve as a -worse-than-worst-case-scenario-
