I dont think you can. but you can change the size and posisiton so it looks
like a minize window.
If UserForm1.Height > 30 Then
UserForm1.Height = 30
UserForm1.Left = 494
UserForm1.Top = 525
Else
UserForm1.Height = 180
UserForm1.Left = 258.5
UserForm1.Top = 203
End If
also make it modeless so you can work on the sheet while the form still
open.
