Of course I searched -- but that doesn't sound like the same problem. I "only" have Yahoo Mail crashing -- not Yahoo Mail warning me about having to revert to Basic Mail or something like what they're talking about in that thread.
However, since you brought up that thread, wherein they recommended updating to the latest version (as always), I have another question, too: WHY IS MAXTHON ALWAYS TELLING ME IT'S "UP TO DATE" when I see on this forum that there are newer versions????
