behaviour of comboBoxes

I have a question about and/or issue with comboboxes on OS X (don’t know about XP etc yet).

As you can see on the screenprint I now have 2 comboboxes with a different look. The lower one was what I always had. The above one popped up today after giving it a valuelist. Could the difference

How come?

The other thing is the size and the background. A transpararent combobox is not really transparent as you can see… And, In order to position and align a combobox with a textfield I need to reposition and resize the box on OS X (not on windows though). This is not the normal behaviour of a combobox as far as I know… Now I change the sizes on startup depending on the platform but I would like to get rid of this…

It is RC7 and OS X 10.3…

ok forgot the screendump and I have additional info.

The new looking box (the above one) popped up after I used the example Maarten posted under http://forum.servoy.com/viewtopic.php?p=2497#2497

Ah, while testing thisI think I found it. Selecting on a value list this way makes the field in fac non-editable. The editbox therefore gets lost…

So, this way of working is easy and secure untill you want the user to edit the value if needed.
