OS : windows 7 ,64bit

the full screen mode . double click the mame64.exe to open the MAME . Before entering any games , typing Alt + Tab ( or Windows Key + Tab ) to switch to the other window , mame will crash and show this information : "Fatal error: Fatal error: Too many live texture instances! (../../../../../src/emu/render.cpp:490)"
