I'm finding that in a viewer with the r2 version of this patch the mouse pointer flickers through at least three different states in rapid succeession when you hover it over your opened inventory and your inventory is still loading. I'm pretty sure it didn't do that with the previous version. - Lance Corrimal On Dec. 5, 2011, 2:43 p.m., Ansariel Hiller wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
