Excel VBA / ComboBox ShowDropButtonWhenNever not working..?

[Young Grasshopper]

Hi guys,

This is a purely aesthetic problem, so not a huge deal, but a annoying one..
I have this userform with a combobox. The combobox's Back- and bodercolor are transparent, since i have a image behind it, becaouse I want to make it look like your clicking the image to open the dropdown.
Combobox is set to StyleDropDownList and the Drop button is set to never show. However, everytime I actually i click on the combox, the backcolor in itself stay transparent, but the drop button appears!
Also, i get the "write-here-animation-line" appears inside the combobox.. This kinda ruins the clean design of the userform.

Is this a known problem, a bug, or have I just misunderstood the consept of "never show"?
Any other smart ways to solve this? I've tried just putting the combobox behind the image, but then i have the obvious problem of not being able to click on it..

Thank you

The style property should be frmStyleDropDownCombo (2).
Then perhaps triggering the dropdown action in the Enter and MouseDown event procedures?

Private Sub ComboBox1_Enter()
    ' The control has focus by Tab key
    ComboBox1.DropDown
End Sub

Private Sub ComboBox1_MouseDown(ByVal Button As Integer, ByVal Shift As Integer, ByVal X As Single, ByVal Y As Single)
    ' The control has focus by mouse click, or user wanted to select another option while the control still has focus
    ' Enter event is also triggered but only when the control has no focus already, that's why I needed this
    ' Preferably, I can avoid this necessity by simply setting focus on the next control in ComboBox1_Change event procedure.
   ' to make sure triggering the Enter event on the next selection.
    ComboBox1.DropDown
End Sub
