Un/Re-installing and unchecking the IE box didn't work, so I uninstalled both LW & java 1.5.0, re-installed java 1.5.0 & then LW. The LW installer didn't ask me to download the j2re, so I thought that was going to work, but no. Same unsuitable runtime environment error. So I uninstalled both again, and installed LW w/o java in yet, and let the LW installer go get java 1.3.1_04, and now LW runs again. However, I lost all the search icons but the All Files one. I'll see soon enough if they come back after a restart.
I'm on an old 700 MHz PIII w/ 256 RAM, and XP seems to really work it. There are 2 users on the PC, and on my side I like to keep LW, Zone Alarm, Peerguardian, and NAV Auto-Protect running. Sometimes another user goes onto their side, and I noticed that even when I'm not logged on, there are mouse pointer/ menu flickering when Yahoo games runs its java applet. I've tried all the obvious fixes, and even had it licked once, using a special driver from Dell so XP can run Dell's modified version of the video card. But since I've reinstalled XP, and apparently Dell doesn't want to help again. (It took me 3 mos. to get the driver the first time)
The flickering problem doesn't happen with LW, but even when the modem's turned off, and there's no I/O traffic, it slows the computer noticeably. I was hoping the newest java would be more efficient in it's use of my poor, overworked CPU.
I'd still like to be able to run LW in the newest java to see what would happen, so if anyone has anymore ideas as to what I could try, I'm grateful to hear them even if I've got LW up now.
Thanks, everyone.
