Resizable window bug

[unsoft01]

Hi.
I make my window resizable using

Display.setResizable(true);

Then in update loop whenever display is resized i set new display mode with size of the window.
The problem is that after set new display mode I can't resize window anymore.
Display.isResizable() returns true.
I'm using lwjgl 2 and amd graphics card.
