The following code should run Chrome minimized, however it works only with Internet Explorer and ignores all other browsers.

Dim oSettings As Settings = New Settings()

oSettings.Web.DefaultBrowser = BrowserType.Chrome

Dim oManager As Manager = New Manager(oSettings)
oManager.Start()
oManager.LaunchNewBrowser(oSettings.Web.DefaultBrowser, True, ProcessWindowStyle.Minimized)


The workaround is to use:

oManager.ActiveBrowser.Window.Minimize()
