Neither the Regular SL viewer 22.214.171.124439 nor the Beta 126.96.36.199931 will install via the installer and only when i completely uninstalled the regular SL viewer and installed from the website did it install so that i am using the latest version... However i have a new graphics issue that is driving me buggy... no matter what my settings i have flashes of texture every few seconds. Whether it's my hair or the sign i'm looking at or a candle or a field of nothingness.. a pompom shape of the textures i am viewing flash wildly across my view bright ... big... and annoying! I have an up to date graphics card that can more than handle SL and all of my drivers are up to date. Hoping this is a bug that will be resolved shortly? Please? I'm mildly epileptic and the flashes aren't something i can watch for long. Thank you! P.s. on a just mildly irksome note no matter what i do i can't update the shortcuts for starting to match my current tilebar favorites assuming that's a glitch?
