Hi. I hope there is still some chance to fix a potential bug after so long...
I don't know if it is a bug in Windows or the control itself, but anyway.
I have discovered that, if a button has icon, text and DropDownStyle set to ddstNormal, the whole toolbar is vanished.
The combinations that actually work are:
- Icon + Text (of course)
- Icon + Text + ddstAlwaysWholeButton
- Icon + ddstNormal
I have only tested it on Windows 10.
The problem is reproducible in your sample: General\MDIApp
My app is normal, not MDI.
Can you please check it?
