I noticed two strange intermittent behaviours running DOSbox 0.71 under Windows Vista. The first only seems to occur when I run DOSbox in fullscreen mode after the machine wakes up from a sleep state and even then not every time. What happens is that sometimes I get an error message from my monitor indicating the temperature and refresh rate combination is out of range (shows 57K and 75Hertz). In the second situation the colors on the DOSbox welcome screen show a red background instead of the normal blue one; this sometimes occurs independently of whether or not I have started DOSbox after the computer has come back from a sleep state.

I can usually correct the color issue by leaving fullscreen mode and then going back to fullscreen mode. When I get the monitor error message, my system is left in a state where I have to close DOSbox and reboot in order for graphics in DOSbox to work (other video outside of DOSbox appears to be unaffected in this situation). When the welcome colors are odd, I can still run games normally within DOSbox and graphics within games appear normal.

I dual boot Ubuntu 7.04 Linux on the same machine and have neither of the above issues when running DOSbox under Linux (the DOSbox version I run under Linux is 0.70)

Any ideas or recommendatons for troubleshooting would be appreciated.
