I have a 386SX with a 387SX math chip. I'm developing a program that does a lot of floating point math. Whenever I have my (Windows) program active, and then select the dos box, and then return from dos, the Windows program gets a UAE and stops. I can repeat this behavior with the Windows calculator accessory - when I'm using the calculator & go to dos, when I return often the calculator program gets a UAE and stops. So now the question: Is this a (known?) bug in Windows? Is there a workaround? Or perhaps my configuration needs some modifications? Does this happen even without having a coprocessor installed?
