I have a BOM in Solid Works 2014 that has repeatedly locked up and prevented me from moving rows into the order I desire. The table is not locked or set to follow the assembly order. The BOM was allowing me to move the parts up and down, then it seems to "time out" on me and stops cooperating. If I manually add in a row it will allow me to drag it up and down in the BOM but still the other parts cannot move. This does not make sense to me. I do have 80 components on the BOM so I don't kow know if it just maxed out or what. Regardless, I would like to know if there is a setting to correct for this. I have already reloaded the BOM multiple times and refuse to do it again.
