Hi All,I just found this topic since I was looking for a solution to this prob as well. I have 2 Nvidia 7900/GT-GTO in SLi config and have the same problem when in 3d mode and accessing any menu. I have had this problem ever since I installed FSx/Acceleration but I only got round to try and solve this just now.There is an extra step to the ALT+ENTER workaround that I have found. I write it as my 2 cents since I see that you experience random crashes when ALT+ENTERing.When switching from 3d to 2d, make sure that the menu is INACTIVE (not shown). To do this, ALWAYS press ALT and hold it for 2 secs before pressing ENTER. It always works for me.If in the meantime there has been found a proper solution to the problem, please be so kind as to let me know.Thank youYiannos
