Thanks for quick reply, though not a fix.
Yes, I keep Firestorm around and am using it now, because ...
After today's non-complete clean uninstall (just an installer run), the SL viewer ran a couple sessions THEN it has again insisted on installing 3.7.28.300847 (the last XP version)
Yes, Firestorm is working fine.
I am going to go look into .log and dump files
+ a clue might be that if I answer 'ok' to the 'you must update with the old version' prompt then I get error that I must have XP or later.
2. (I know, I know, should not have 2 issues in 1 posting) I will look into this issue separately, but to answer you
this issue has happening before and after cleaning out the dust bunnies from the fans.
Draw distance is way lower than on FS and many other settings that some other posting have said.
SL viewer is the only app complaining about vid card. My laptop really does have some graphics driver issues, but SL viewer runs ok.
