Does anyone checked the bug?
I have the described problem with selecting values on Mac with exactly the described behavior (windows and keyboard works, but the dropdown field on Mac does not work)
I'm using Scout RT Version 188.8.131.5240611-1401 - which should be Luna "latest" (anyway, definitely higher than M5...)
To give some more details:
1.) Click on the "magnifier"-button only works when the text-field has the focus (the caret is in the field) - so you have to click into the field first and the you may click on the "magnifier"-button and the value list is showed
2.) You have to click twice on a value on the list to choose the value - this only works when the text-field is empty
3.) When the text-field is not empty and you choose another value, the textfield does not take the new value. so, you can choose only once! You can delete the textfield by hand (using del from the keyboard) and you can choose a new value, but you're back at point 2.
4.) Already mentioned above: clicking down and then hint enter works
5.) sometimes the proposal-list is empty instead of showing the list of values. This occurs when the value in textfield is completely marked and I try to choose another value, this fails (see 3.) and I open the list again.
