When I wake my laptop from sleep mode, it appearss as though explorer.exe is acting up, and all of the windows seem to mend together, and typing sometimes lags, however, when I end the explorer.exe task and start it up again, it does not solve the problem. I'm not sure if this is a Windows 7 problem or not, because when I got the laptop it had 64 bit Vista but I immediately uninstalled that and installed Windows 7 because Vista is terrible. But the laptop has been acting this way as long as i can remember.
