Check Input

[funkynut]

Code:

If KeyCode = vbKeyF5 And frmMirage.picChat.Visible = True Then
        frmMirage.picChat.Visible = False
    ElseIf  KeyCode = vbKeyF5 And frmMirage.picChat.Visible = False Then
        frmMirage.picChat.Visible = True
    End If

You forgot to check if F5 was being pressed when visibility = false, therefore, whenever it checked input, it would check if visibilty was false and set it to true
