I have had countless problems with ACAD 2008 and thanks to folks on the forums they are all fixed!
If your ACAD is.....
Acting very slow, especialy plot, publish, undo and attipedit try relaoding your plotter using the wizard. I don't know why but it works.
If mspace/pspace is very slow to regen try ALTFONT and type in romans.shx. this did wonders.
I am now back in love with cad and can fianlly make those deadlines agains!
If anybody else would like to add something they found usefull post it.
Thanks to everyone for helping me out!
