I'm with Eric. There's got to be some sort of "floating" spell check device out there that can be minimized to sit on your Task Bar. Then just highlight the text, after initial composition, drag and drop.
Spark, do you know if UBB is planning a spell check in the upcoming release?
Eric- Congratualations on making the switch. UBBis kinda like the NRA. We can grumble all we want, but it's the best alternative out there. Zach's done a fair amount of customizing also. Keep us abreast of your ideas and changes.
