Dual monitor - force new windows to always open on primary monitor?

Question

I use my secondary monitor to watch streaming TV in internet browser windows.  When I have finished watching streaming TV and the secondary monitor is switched off, Safari still opens new browser windows on the secondary monitor by default (presumably due to the fact that the last active browser window was open on the secondary monitor).  This is irritating and means I have to switch the secondary monitor back on to drag the new browser window back to the primary display.  The secondary monitor is connected by VGA.
This is a minor niggle, rather than a major issue, but it is irritating nevertheless!  Does anyone know if there is a way to force new windows to always open on primary monitor, regardless of where the last active window was?
Any help much appreciated.
Many thanks,
Ben

After many days i found solution:
Run the client and get it set up the way you prefer, or Open your saved RDP file
On the Display tab, choose a non-fullscreen resolution.
On the General tab, click "delete these credentials", if possible.
Click Connect .
You will immediately get a local login dialog. Leave it blank and click
OK .
When you are connected and the remote login dialog appears, drag the window to the desired monitor.
On the remote login dialog, click Cancel . The settings dialog should reappear locally.
On the Display tab, you can now choose fullscreen.
You can now save your session with the Save button on the
General tab, as well as save your login credentials.
Try more times ,worked for me.
