Re: Dos App hangs with msg X: expose event

["anon permutation" <anonpermutation@hotmail.com>]

Hi Ryan,

I have posted the bug on sourceforge.  Please take a look.  Thank you for 
helping out.

I have encoutered problems while uploading even 256KB chunks, as a result, I 
have only pasted the top and bottom of my log online.  The complete log is 
about 23MB.  Is there a place where I can email you the file?

If the GP fault from run_vm86() is ok, does that mean I can just change the 
codes that handle the fault in vm_86_GP_fault() to do nothing?  Would that 
allow me to work around the problem?
