Qt Creator 2.6 rc New File or Project dialog resize problem

1. Launch Qt Creator 2.6 rc
2. Click File --> New File or Project menu
3. Try to resize the dialog to be larger, by clicking-and-dragging on the bottom-right corner of the dialog.
==> The dialog immediately auto-resizes to a smaller size, and any further attempts to resize the dialog via click-and-drag fail. One workaround is to maximize the dialog by clicking on the green button in the upper-left hand corner of the dialog's title bar.
