![]() On 10.11 in 64-bit mode, showing a frame with a PSMTabBarControl instance somehow causes the event loop to become occupied on mouse movements, so that moving the mouse in a `2htdp/universe` program is slow when more than one tab is open in DrRacket. The modern MMTabBarView widget doesn't have that problem. Also, the MMTabBarView widget has a Yosemite look (to replace Aqua). |
