If you removed all versions of Java, did a registry clean, then installed the offline Java & still problems, then either a different version of Java or a setting on LW.
Have you tried (a) setting LW to run as Admin. by right-clicking the program file. (b) tried different compatibility settings depending on which windows you are using. You didn't specify. eg: right-click LW change compatibility to NT or win 2000 or XP, etc.
The problem 'might' also be your video card settings.
