You can use /debug @debug to open a debug window and then log the window. That *might* give you an idea of what's happening when it crashes. But it probably won't be much use. Most crashes are likely to be caused by a DLL, so if you are using a DLL, I'd recommend checking to see if that's still working correctly in the newer version of mIRC. Note that DLLs often need to be updated when new versions of mIRC are released, depending on what the DLL does.
Thank you, and no /debug isn't helpful :\
