Thanks for your effort.
Truly when I use VLC in full-screen mode the start tip,left bottom hot corner doesn't appear when I move the mouse to left bottom corner,as you said
not to mention that in full-screen mode the play button is in near middle of bottom of screen.
I use VLC 2.0.8 32bit version in my laptop,and it is not an app.
but I,for example;use VLC in Maximized size not full-screen mode,so the Start tip appear,so if I am not careful and click on Start tip I will go to the Start screen while my video is still playing.
I see that many one have this same problem and posted about this on other sites
I am pretty sure,there must be a registry value for bottom left corner,that if I change it,this corner won't function anymore.just like other corners have registry value corresponding to them in Regedit.
so the question is.where this corresponding registry value resides.
