Hello, after long time working with Dosemu 1.3.4 I have just updated to Dosemu 1.4.0.1 and found the following regress compared with !.3.4: 1. Chess program Rebel 12 fails with the message Interrupt 0CH Stack fault Errorcode =0000, with the some additional information 2.Chess program Vchess fails with the same message like above INTERRUPT 0CH, STACK FAULT error code = 0000 eax = 0000000C esi = 000000EF flags = 3046 ds = 00E7 ebx = F000E987 edi = 0010DAB8 eip = 00004476 es = 00E7 ecx = FFFFFF09 ebp = 00187E30 cs = 00AF fs = 0000 edx = 0002CDB6 esp = 00007D70 ss = 00DF gs = 0000 F:\vchess> The difference between the both cases is, that after the crash of Rebel 12 also dosemu crashes, after the crash of Vchess the dosemu still works In Dosemu 1.3.4 the Rebel12 was working (with some mouse problems, but it was possible to play games. With Vchess I can play a game without using the mouse, moving the mouse dosemu crashes (as far I remember, Stass Sergejev has made a patch for it, I should have anywhere. Big question: is there somebody who can fix this issue?
