Guild Wars 2

Hey,
I’ve been having this problem since I first began playing guild wars 2 (release). My game runs perfectly fine in full screen, I can open everything in-game without it crashing, although when I put my game into windowed full screen (because it’s a lot sharper and enjoyable to play on) it runs perfectly fine and I can play the same as full screen except when I open certain in-game features such as the ‘Hero tab’ (H) and some of the Black Lion Trading company tabs it immediately crashes and displays the crash prompt giving me the option to send an error report to Arena Net (yes I’ve sent multiple). I’m just curious as to why these issues would occur in only the windowed modes. :’(

Thank you for any future assistance!
