Fix the focus issue on RDP Client from the AxInterop.MSTSCLib.dll

If you ever worked with the RemoteDesktop Client from Microsoft, you probably ran into this bug.

When selecting another component on your application, the client of course loses focus, but when you want to select the client component again, the only way is to use the TAB button, you won't be able to select the client component with the mouse button, so here's a fix. ;)
