Starngest thing. I ran the 64-bit beta for a number of months and spellcheck worked perfect. Started running the 32-bit version and I get a totally screwed up custom.dic after I run spellcheck. I have tried repairing it but no luck so far. I only changed to check how my old add-ins ran with 2010 as they're all 32-bit. Probably just pop back to 64-bit.
