right click menu on windows tablet

Hi, thanks for the great new client, unfortunately when i right click on anything the menu tries to pop up but dosent, i get a blank section for a second with no menu items. of course tablet pc have no mouse but that should not stop right click menu working as it works in all other programs by holding finger on the touch screen, any help appreciated. thanks.

This is a similar issue on Windows 8.1 with a dual monitor setup. Whenever you right click on a file to download it the pop-up menu appears on the other screen (I guess because is configured as the main screen) even though the client is running the GUI on the other one. Is there a way to make the right click pop-up menu to appear on the same screen as the client's GUI?
