strange error

[tomo black]

hi, i have written a swing application, which runs perfectly in college on XP and win2000 but when i try to run it at home, also on a win2000 os, it throws this error.
In the application if i use the default size then the application appears(at least the title bar does) but if i use "setSize(300,200);" or try to maximize it or drag it bigger then this error is thrown.
i've put it through google but it came up with nothing.
any ideas as to what it means? im using java1.5 beta
thanks

This kinds of crashes are generally caused by video driver bugs. Make sure your video card's driver is the latest available. If it is, you might try turning down the acceleration level (i.e., the "more compatible/better performance" slider.)
