I'm a bit confused. I've spent countless hours with this, and haven't found a solution for it yet. I've come across a few various bug reports in the forums, but they've been closed with no action response, and other various posts have stated that it doesn't affect them, so I'm not sure what the current status is on the problem.
Anywho, the problem is that it appears with all different pickers, including the datepickerfield, if you're using a relatively recent version of Chrome, you are unable to select the last element in the picker. That is, if you select December, 31, or 2012, it immediately pops up to the element just prior to that point (ex. November, 30, or 2011). I've tried this with Sencha Touch 220.127.116.11, and Sencha Touch 2.1.0. Both still have the same issue.
Are there any available overrides or anything that I can use to resolve this problem? Apparently it only began affecting Chrome after version 16 or so, and has persisted all the way until the current version (currently version 23). It doesn't affect Safari, or iOS or Android. However, my user base, as well as my testing platform, is heavily Chrome dependent, and has made using the field difficult, if not impossible.
Any help or ideas to fix (or at least band-aid) the problem, would be much appreciated. Thanks!
