ok, i'll do my best...
i've created a few symbol block libraries and we've been using them for several years. my co-worker has recently begun to have problems opening the block libraries.
he clicks on the autocad design center button, it begins to open, but instead of displaying all the blocks, only 2 or 3 of them are loaded, then it stalls and ultimately freezes cad so he has to use the task manager to close down cad.
he's tried opening it using commands and through the cad today screen, yet the same thing occurs. he can't open the design center and has to resort to opening our block library and then copy and paste the entire set into his drawing. it works, but he'd prefer to use the design center since it's quite useful.
thanks for any help. i'm unsure what else to describe, i hope it's enough for suggestions.
