As stated on the subject, this isn't an issue of keys being stuck, as it's persistant on all viewers (Phoenix, Firestorm, and SLViewer, and Exodus.) Only upon log on... And on all avatars. I removed all viewers and wiped all data and preferences and cache manually after, then reinstalled simply SLViewer, all seemed to be fixed until inventory loaded, upon relogging back to being unusable.. I've removed all inventory worn on avatar too, so it's nothing to do with what's worn, but alas this seems to always happen just after relogging upon loading inventory on CLEAN instalations, simply removing preferences and cache will stay unusable even whilst loading inventory (Fine at logon screen, and all other apps always however...) What's wrong? EDIT: @LoveAngeL Lyre - I'm using Windows 7 Ultimate SP1, specs are... Intel Core i7-870 OC'd 3.6GHz, 16GB DDR3 RAM, and 2 x nVidia GeForce GTX560TI on SLI ... Internet is ADSL 1.3Mbit. It's unrelated to lag, and as I said, modifier keys such as CTRL, SHIFT, ALT don't work, pulling it with the mouse shows that lag isn't an issue... @Peggy Paperdoll - It is persistent throughout the last few weeks, many reboots, resintalls, and even a format has taken place since... Thanks in advance.
