Widraw from bank glitch

I found a very annoying glitch going on at the moment. It’s kind of hard to explain but I’ll do my best.

When I open my bank a big part of my screen is taken, a big part of my chatbox gets hidden under my bank interface. Now, I want to widraw an item and this Runescape item is on the same place as where my “Guest Clan Chat” tab is. Like, my bank hides the complete chat but the item is on the place where the Guest Clan Chat usually is.
So I click at this item to widraw it but my click on the item gets registerd as if I click on the Guest Clan Chat tab. So it’s like I click through my bank on the object that’s behind the bank.

Another example: I tried to move an item in my bank to another space and this Item happend to be on top of the location of my action bar. So I clicked the item, hovered my mouse over to the place I wanted to place it but instead of grabbing the item it grabbed my action bar as if I wanted to move this.

I hope this is clear anough, I’m not sure how to explain it any better, sorry for that.
