Dos App hangs with msg X: expose event

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

Hi,

I have a dos app that hangs under both 1.2.2 and 1.3.1.
The hanging is pretty random, but in one case, it
seems to relate to X: expose event.

Basically, the app sometimes changes resolution in
order to show different differnt objects. We find that
sometimes, the app will hang when this change of
resolution is being executed.

Normally, when the change of resolution is successful,
we find maybe 1 or 2 "X: expose event:" message.
However, when the app hangs, there are many "X: expose
event" messages in a row.

Kernel version is 2.4.24
X is XFree86 4.3.0.1

Dosemu itself seems to be fine even after the dos app
is hanged. It will still respond to keys such as
alt-ctrl-page-down.

Please help. Thanks.
